In a hundred years from now this is the channel they will use to teach about old cars,
maybe not even 100 years. Self drive electric cars will either be our lifetimes or our kids'.
He is good a lot of these guys on yt are idiots
This man is showing me how to rebuild my d250 with a 318 and Im so thankful.
Uncle Tony splashing gasoline everywhere while dude throws sparks with a grinder outside of camera view. Brave man.
Uncle Tony you have a wealth of information your the best!!!! And thank you uncle Kathy for recording all of this for us!!!
Uncle Tony!!! I really wish i could spend just ONE day with you, being a shadow, turning wrenches, wiping things down (i truly wouldn’t care what id have to do😂) i’ve learned so darn much from you, through the tube! the least i can say is THANK YOU SO SO MUCH! please keep making videos, never stop! between you, an my old-school grandmother i’ve learned everything to slowly build my 88 i-roc z28 / anything to do with an old-school car down to the 60’s! you are the man! keep killing it as always!! i always look forward to your videos! sometimes it gets me the right amount of motivation to be old school. I even went from TPI to carb just because it gave me more videos to watch an pay attention to!
Filming in the garden will give Uncle Kathy a rest too. You can tape the camera to a chickens head. They make perfect 3-axis gimbal stabilisers, better than anything made in china. No matter where you move the body their head stays still. The perfect killing machine.
Perfect filming machine?!
That's clucked up
The tips and tricks you share are pieces of gold. Thank you uncle Tony
More on heads please. Thanks Tony
I would still check the seats to make sure they were seating even on exchange heads before putting them on.
Even the Good name brand heads New sometimes are not seated proplerly......sad but True!
having a bunch of ways to come up with from any outside of the engine the health of your heads big picture wise is fantastic. Perfect for head shopping when you get a new ones to check check the validity of parts great job Menard
I love how Uncle Tony uses gasoline to rinse and check everything. It's a good thing he's not a dentist.
Or a smoker.
@@stevendouglas6593 he is a smoker
😂😂😂😅😅
I Love Watching All Your Videos Tony - Keep Up The Great Work ! !
Broken stud a good candidate for battery charger/ tub of water/ baking soda trick
A nut an a few electric spot welds usually works but not always.😎
@@bigbear5510
Haha I usually go thru 3-5-8 nuts or so before one sticks good , and by then the heat soak is helping too.
I did see a neat trick recently that I'll have to try , and that's tacking a washer on the (flush broken) stud first , and then adding a nut to weld on.
@@MrTheHillfolk I've seen that one too. A few heat cycles with a propane torch first helps, sometimes that all it takes This one is broken off inside the head a little bit though. Maybe Uncle Tony will share his secret trick with us. 😎
@@bigbear5510
I'm pretty sure he's got many tricks up his sleeve for extraction 👍
Thank you for the little tips that you don't find in the books, or even online,(for the most part)
Like the valve guides, there are many vidd and literature about seats, porting, warping of the heads, etc. But almost nobody mentions the valve guides! Especially about machining them for a high lift cam.
cooking up some Mopar goodness in the UTG Kitchen!!
Small block mopar pick up a set of the newer Magnum heads and miles ahead of the old non hi-po ones.
You answered allot of my questions, thank you learned allot so far
Thanks tony that's why I running 68 7a heads on my 71 350 olds love the vids bro 👍
Yea, it's his fault that im obsessed with finding a 1973-74 Duster now. Slt6 or 318 dont matter. Had one when i was 17 and now i want another one like it. I care nothing about numbers or any of that rigg-amarole.
Just a straight duster not full of vent holes.
Olds fan here, how does that motor run
@@williamtownsend4978 not the fastest butt sound the nicest about 325 hp ✌got that Oldsmobile sound that I love
I love watching these videos, ive learned so much. Thank you, I’m building a turbocharged 5.7 Hemi and you helped me open my mind to using everything that’ll work. Soon as I’m done with that, I wanna build a Turbocharged 5.9 bmw. Lol
I've always used the dishwasher to clean parts. Just run a cycle after and bingo...no evidence. I found it works quite well for K&N air filters...spic and span.
Did I hear right? You’re using 360 heads on this 318? Looking forward to seeing how this one turns out.👍
I would have used 318 heads ported with bigger valves just for the port velocity alone 360 heads work ok but not until about 4000+ and you need higher compression I know I have built many through the years. On a 318 your compression better be at the minimum 10:1 if you want to see the benefits of the bigger ports.
Great video! Thanks for dropping some knowledge on us
"straight out of the box" You hope.
no smoking in this video.... good thing.
Yes don't want you big boys to cry like normal
@@79tazman also, he pours gasoline all over himself.
A cigarette won't ignite gasoline in my experience. Filled a bucket with gas and threw a cigarette butt in it and it just put the butt out.
I agree. For any engine that has way over 200,000 miles... the exhaust seats are going to be worn out of useable spec. Better to just replace heads with low mileage units from a wreck. DAMHIK. Fooling with them is a fool's errand. Valve springs will be sacked out too.
How about checking seats for cracks, ie magnums. Instead of gas use wd40 to check how well the valve seals then evenly warm the seats and the wd40 will boil out of the cracks. With the heads disassembled of course. Love your channel!
Watched previous parts …. Great tips !!!
Uncle Tony, this series is great. i have watched every minute. i am eventually going to have to deal with the heads and rings in my studebaker 170 six cyl.. it was run with a flooding carb most of its life, according to the records that came with it. It had more carbon than a burned down forest, and more leakdown than a drained lake. and blowby good enough to make the oil a high grade fuel. assorted rings and valves were sticky. since last June i have started and drove it a bit here and there, and it came around last month, believe it or not. The Daytona universal carb was a better match than the original Carter RBS unibarrel.
Good stuff, Tony. It's funny, I've been seeing you hold that bottle of gasoline in videos for a long time. It always looked familiar. And today it is confirmed, it's an vintage AMWAY squeeze bottle. That thing must be 40 years old!
UTG got kicked out of the kitchen
AND IT WAS HER DAM IDEA IN THE FIRST PLACE😂😂😂😂😂
Compressed air directed with a nozzle will show you leaks and no fumes when you bring it back in.
A funeral home can supply polished granite to dress cylinder heads. Use spray adhesive to secure sandpaper and slide the head. They can get you granite in any length you need. To check the deck surface use a marble base that is used in trophies. I get these trophies from yard sales. I also use the granite slab to sharpen curling rocks. See my videos on CZcams.
Yrs ago I bought an old Sioux valve seat grinder kit. It kinda sucked compared to a set of cutters but it would do in a pinch. Cheap too
Looking forward to watching the gasket matching. Want to do that to my 318.
With luck I will have a video up next weekend of machining down the guides on a cylinder head and cutting spring pockets for extra springs.
I remember Mopar came out with hardened valve seats in 1973, but recommended using leaded gasoline every third fill up to coat the valve seats. It takes a long time to wear even unhardened valve seats though.
Not in my experience. If you drive it every day it doesn’t take long at all. Three months and it worn, six months is worse. A year and it’s worn out. Remember, this is my personal experience. The best thing is to put in hardened valve seats or a late model head.
@@ryandavis7593 Some engines went to rotating valves for unleaded gasoline, but setups usually don''t hold the valves as securely as positive valve keepers. Ford went back and forth with rotating and non-rotating valves in the Cleveland M series engines.
@@ryandavis7593
Daily I deal with this shit on air-cooled b+s engine powered generators powered by lp/Nat gas.
The recommended valve adjustment every 100hrs.
I've seen em not start in 180hrs without an adjustment.
Not sure how the new customers generator I fixed last week ran until 380hrs without an adjustment.
There wasn't one loose rocker at all and they gotta be .006🤦
No compression, fucks up the intake vacuum signal and the regulator won't allow proper fuel draw.
See it all the time , it's surprising how much shit they can handle actually.
But wearing valves so bad that the adjustment can close up totally by 200hrs is nuts you're not doing your valves any favors.
That's what people don't realize about LP, it sucks as an upper end lube and wears out the top end alot faster.
That gasoline is actually lube for the valves.
I've had plenty of gasoline units with plenty of clearance at 100hrs, but still set them cause you're there.
@@ryandavis7593 Mrs. Landy, his 64 Dart has unhardened seats and literally one million miles of driving. I've had excellent luck with unhardened seats.
love the vids.
Its -5deg with a -34 wind chill here its cold as all get out
I'm in upstate NY and laughed at my uncle in Austin Texas just now.
Yup, it's 32 here and 25 there....
and he sent a pic last week or so of about 2" of snow.
If a machine shop uses a belt sander to resurface a head you better find a REAL machine shop.
Most use a Rotary cutting machine with the head or block perfectly leveled in the fixture.
Yep and I've seen a few heads that were straightedge flat longways but out of wack when the straightedge was placed diagonally across the surface
Not me but a coworker did that once.
One of his buds swung in at lunch and asked him to 😮
Chev 350 won't care 😁
He just wanted all the gasket goop and shit off the surface real fast.
Cool part was the dude flipped him 30$ and I got free lunch for being quiet 😝
I was told harden seats are needed in high rpm engines and tow engines things like that but for everyday driving and once in a while getting on it won't hurt anything it's just the high load engines like fleet vehicles tow rigs and race cars harden seats are necessary
If you drive it often it needs hardened valve seats.
Does anyone use valve lapping compound anymore?
i am sincerely going to give that a try on my studebaker 170. i saw a vid of a guy doing that to same engine, with great results. seats are not hardened.
I always cut a 3/4 degree interference angle when grinding valves and seats. Lapping the valves afterward doesn't hurt but doesn't make them seat any better.
@@jimmyraythomason1
Could you please educate me on why they won't seal better?
I'm kinda disappointed your not going to show how much fun it is when you convince yourself that you can replace bad valve guides at home
If they are replaceable, it isn't very difficult with the right tools. Different story for those that have to be machined.
Every kid should start off cleaning parts builds something haven’t figured it out yet what exactly.
Thanks fer all tha info
Quick question
How much lift can one run with stock 360 mopar heads ??
Nothing over a .590 lift. Head stalls with anything higher
He says .540 is max lift in the video without trimming the valve guides.
@@johnwilburn They watch but they just don't listen!🙄🙄😲
about 9
I do listen n heard tha .540 lift about tha guides but wondering about tha springs n retainers limits
Thanks
So glad i found this channel.your awesome ...refreshing my brain, i have quit a few 318~n~ 360s from the fun
years hopefully i will start rebuilding them when finances are b3etter.you explain thigs so well ,i can understand everything.good on ya for helping the little guys.God bless everythin yu do! your my fav channel now.much love from south australia.ox.
Show us a good method for broken stud removal. Pls!
Heat it with a torch, penetrating fluid, left handed drill. Or if you have access to a Bridgeport and carbide end mills that’s probably the best
Great information Uncle Tony!👍👍 Hello Uncle Kathy!👋
When checking the valve guides make sure you have a good valve in hand!
I was wondering what kind of heads you were going to using on this engine. Thought that you might be going with some aftermarket high performance heads. I'm sure ya can get these to flow just as good, if not better!
Lookin' forward to the next video!😎
Uncle Tony, someone showed me the gasoline trick for checking valves when I was younger. But then he took shop air and blew it on the back of the valve to check and see if we would get air bubbles in the gas. Does that make sense to you?
I wore sherpa and sweats over that. T+shirt, sweatshirt, and a heavy chore coat over that. Thinsulate boots. Sun actually came out here first time in a week. Made it all the way to 12 deg. Cold wind though. Next three days sposed to be much colder. I thought hardened seats weren't until '72-73?
As I am sure you already know sometimes those bargain rebuilt heads are not always such a bargain they need to be gone through to make sure they are ok. This also applies to the aluminum heads as well brand new out of the box I have seen them with bad valve seats the wrong springs and or retainers ect.. When it comes to heads ALWAYS check everything because there is nothing like dropping a valve on a brand new rebuilt engine to make your day.
It is extremely cold 🥶🥶🥶. It was never this cold in December!!
Its a balmy -15 here right now ,no flies , no mosquitoes , oh yeah
Oops. I shouldn't use the kitchen hand mixer to hone cylinders?
A new floor, Yep ;0). The heavier engine stand with two wheels up front is far safer on the card board. Made that mistake positioning /wrestling with a 750 # stand with one wheel up front when turning the block over. Whole thing tipped and I had to catch itin my arms before it took out my knee's, my stocking feet and the floor. The wheel trail in the wood hall way floor from my room remained for many years. Not like working on a concrete garage floor in any way. Keep that in mind.
Surfacing heads on a VERY flat table or piece of glass has worked on a lot of sub 10 second cars I have seen especially on the import side. It does indeed work.
So why were those two end exhaust valves severely mushroomed? Something was definitely not right there...
Probably collapsed lifters, allowing lash and hammering .
Most likely the rocker shafts were full of sludge or ground up plastic from timing gear and or valve seal material. Therefore starving oil to the rockers and valve tips. I've seen it before on a big block. Inside of that engine was disgusting plus timing gear was thrashed.
If those heads could talk with those mushroomed valves.
are those valves mushroomed because someone has been whacking it with a mallet to unstick the valve?
Bent or misshapen rockers?
You're gonna have to whack the hell out of it to mushroom it that bad
@@MrTheHillfolk lack of oil
360 heads?
So, are the heads, crank and deck height the same as the 318 and 340? Thank you in advance.
360 cranks have larger mains and stroke. 263,318, and 340 all use identical cranks some cast some forged. Then heads depend on year and what the engine was put into. For the most part 318 heads are small port/valve. 360 heads are larger port/valve, but have larger combustion chambers, 340s normally have large port/valves with the smaller chamber. Then 273 are normally small port/valve as well. That’s just typically what you’ll find, there are many different LA heads that got swapped through all the different bottom ends
@@tl5108 Thank you
How do you know the seats are good in those heads with the valves in x ray vision or you just know? What about valve seat cracks between the valves I have seen many old heads with cracks between the exhaust and intake valves? what about lapping the valves
believe that he actually thought the height of the exh valve in the combustion chamber was very adequate and represented a perfect shape valve seal underneath
If a 440 overheated to the point there was power loss, and everything returned to normal once it cooled. Was the loss head expansion or was it gas being boiled in the carb
Right on
Are the heads for 3 10 good?
CZcams commercials are as bad as television.
because its same people
Thanks explaintion beats displaysion
I have a question regarding a 1965 Buick Special 300ci, and my son swept the valve spring (1/2) keeper into the garbage. I went online and to all x3 auto parts chain stores and those clerks are absolutely useless outside of entering a UPC # and ringing you up for the said item.
So, how do I SIZE or look up the exact half keeper or any other hardware like nuts and bolts that will need to be replaced?
What are your thoughts on the valve rotators? I ditched the ones on my 302 heads when I changed valves
I can’t understand the purpose behind them. I ditched them as well. If u put a larger lift cam in, you’ll just run into coil bind and valve train clearance issues sooner with them
Oh I didn’t realize this is just 35 minutes old.
I’m building a 440 6 pack for my 69 roadrunner and I have a question what is that brownish primer you use on your engines before you paint them?
Rustoleum
czcams.com/video/3NQyzp5ViNs/video.html
Gliptol.
@@ryandavis7593
Tiny said he used Rust-Oleum rusty metal primer.
Glyptal is like 50$ a quart and supposedly he said the Rust-Oleum primer works about as good.
Is there a specific fuel additive that you believe in to treat the valve seats instead of the lead in the fuel???
Can you do a tool/toolbox tour, I want to see what kinda tools you have
I can attest to the reman heads. Cylinder heads intl in Texas will send out a reman head for $200 with no core charge. It’s cheaper than sending your head to be replanned and three way cut which I was quoted at 600 and I had to completely strip it. You can buy hand three way cutters and reamers and use the Emory clothe To replane Plus the valve seal tool along with the spring compressor but that’s
What brands do you recommend for cylinder heads? Both reman and new? Marketplace out there can be scary, would love to know who you trust.
Tony I want your professional opinion. does it affect flow like I think it does if you where to take the 318s 2 barrel intake off and put on a 360 4 barrel intake ? I know you can do a 318 intake on a 360 and it will boost torque . also running 340/360 exhaust manifolds on a 273 / 318 heads will cause leaks/ burn outs of the gaskets just like with the headers since the ports are different ?
I'm buying a 1998 Dodge Durango 4+4 ,either 318 or 360,with 200k miles, should I put a set of refurbished heads on it? I want to drive it to Canada from Texas? Any opinion on should I get the 318.or 360 model? It's going to be a 98 to 2001, I don't want any newer because of the 4.7 motor I think is junk!
Uncle Tony lives on a carefully balanced diet of meat, petrol and tang.
You forgot a lot of coffee with a lot of cream and sugar.😉😎
Coffee and cigs for breakfast. And maybe a poptart
That is a diet of champions.
Tony you forgot spring tension or loss of from long duration unturned long blocks as an example
He will probable cover that in another video. This was about the heads not the assembly of them.
@@bigbear5510 the video was about assessing the condition of the heads and the springs are as much part of the heads as the valves they hold in place don't you think ?
@@waynefergusson9987 You would check the spring pressures once the heads are disassembled. They are components for the head and parts of the valve train. So it could go either way depending on whom you ask.
IE; Is the glass is half empty or half full?
We will see what happens on an upcoming video.😎
The liquid in the combustion chamber to see if the valves are seating is no good, you can get them perfect and as soon as you bolt the head to the block the seat WILL distort! and the seal is GONE! we proved this many times to people that "know" better than the machinist that was running the SERDI Seat and Guide center all day every day!
Get some fresh heads and pull a vacuum on the port and then again after it's bolted to the block and then after the engine has been run and see for yourself.
I know much about cars but oil change and spark plugs ...so one day my neighbors came over and sold me a part that they claim to make my car faster ..1500 bucks later i see my car come back sounding like a muscle car and i open the hood and i had like 3 new parts ...im told new carb and new trick flow and headers to go with it...they are pair of brother who race and build for a living and seen i liked to go fast but my car was too slow ...i have 2x the power on it now ...turns out they gave me bunch of day old racing parts and they keep adding stuff...last week i got a whole distribution system for more power ......im learning fast too....im gonna buy a second motor to build up with em...just in case .....i have a 1988
Si Bueno!
@ 10:16 ... Thats what she said.
😂
9:05 How do you know a mushroomed stem isnt hiding a sunken valve seat problem?
@Superduper DavidMiorgan How do you know a valve that is sunken already... doesnt also have a mushroomed stem that is now at the same level as the rest, because the seat is sunken and the valve stem now sits higher despite being mushroomed?
Didnt you read?
Valves can have multiple problems...
@Superduper DavidMiorgan Welp you didnt learn much about communication, reading comprehension or sharing knowledge in 60 years did ya? Was 60 years wasted, cause no one G.A.F. about your experience.
i llove thge emory clopth, but there is a guy on youtube who lays a flat sandpaper surface and slides the head back and forth.
Darn I'm trying to remember his name, is that the guy who does the cheap fixes for people who don't have much money?
I wanna say he's in Florida
Where is a good place to buy heads for my LA 318? Rebuilding it for my 86 W250.
No Sunday night live?
amoco had unleded gas in the 50s!
Is there a way to adjust the timing without marks? I took the chain out and my stupidity allowed me to turn the the sprocket s individually, which turned the cams. Now I have no idea where I am at. Call me an idiot because I am. 2015 Chev malibu 2.5
Hey Tony are you going to go to the indy mopar show in March?
This comment is posted is for John Woodworth.
Personally I blame squirrels
Do valve ever hit pistons on stock 360?
I have set of head 434923 cast number need help find info they have 202 valves
sorry i typed the previous statement before you noted the same thing.
Hello i have a chevy 350 block that need new heads
Can i get the old ones off put new ones on adjust the valves and i am good to go ???
Assuming nothing is wrong with the block.
@@Shamilt3 to my knowlidge the block is ok one of my valves is tikking according the garage one valve stem is no good anymore its wornd best thing to do is buy me a referbished one the say
@@wasitipico8742 Yup, buy a loaded head, and get it done.
What???? Is it minus 40 there?? It is up here in Winnipeg , Manitoba, Canada, and I just was crawling under an 97 Jeep Grand Cherokee.LMAO
LOL, You Canadians and your cold weather!😉😉😂😂😂
Just kitten ya! I like cold weather just don't care to wrench in it.😎
-40c in Saskatchewan here too
What's the chances of having you do, and explain your doings on the cost overall for heads? You actually make these heads perform the same as bought ones. Me as a viewer can come up with a few bucks here and there, but not the dump of thousands at once...
Possible rare heads episode? (Your welcome to use common heads as your example)
Am I poking too far?
Very cool UT! Can't wait for the next one tho!
Problem is the 1500.00 heads usually have piss poor valves jobs and tight guides. Need another $300 before you can run them.
Yep. Found that out the hard way.
Quick question Tony. I have a 64 polara 4 door. It's equipped with a 318 poly. The current poly smokes and drinks oil like a rockstar. I have another poly I can plunk in but I also have a 73 360. I'm conflicted on which way to go. Could you give me your opinion on which way to go? The car will be a daily driver but I'd like to hit the track on occasion and parts for the 360 are more widely available and more affordable. I do love the poly though. What direction would you go?
Sounds to me like you need to find another car and build two!
do you want to sell 1 of the polys if you dont use them
Your still here thank god. Probably best for your health to stay out of the kitchen try the living room. LOL
Listen and learn from the Legend of Gear head Monk..
Oi oi oi
If we buy recon heads or aluminum heads should we take them to a machine shop to have them checked over?
I’ve never bought any, but I have heard this also.
Yes.
Yup
Most definitely and make sure the water jackets don't have residual cleaning abrasive falling out , I use a quick shot of shaving cream in all the deck side water holes in a head, keeps any crap from falling in the fresh cylinders and even though most are cut with a 3 angle knife these days ,check valve seat concentricity , you might find they need a light touch with a stone to be perfectly round as the lifting of the knife creates a small irregularity on the seat surface ,but thats just me
Poor man trick for resurfacing head get a piece f broken granite counter top they are cut dead flat glue diamond grit paper to it works like a charm
That’s a damn good idea actually
We didn't punk out, we're just smart enough not to freeze our a&#^@(*@^ off.
