Not really a complete episode but had to do some work and figured I would give a little insight on how I port match an intake manifold.

Thanks for being a great dad for your children! Nice port matching lesson too!
Come on guys... people hand port their intake manifolds AND cylinder heads all the time and have for many years with tons and tons of success. This is a tried and true way to genuinely get more power out of what you have. It doesn't NEED to be done by a CNC machine and if you match the gasket to the head and trace the outline of the gasket to the intake manifold ports it'll be fine. I don't get the hate honestly.
They dont understand the true process. Hell the cnc port designs generally come from ones done by hand.
You would think anyway but about the time you hog out the gasket area too much it screws up the port velocity and that's a bad thing

The Fab Forums by the way you enlarged the holes how much power you think you added
Nicely done video. You describe things really well and make it interesting.
If you're open to feedback, one thing I can suggest is using a face shield in addition to the safety glasses. Several years ago I was porting iron Ford 390 FE heads to match the new valve sizes. I was using a die grinder. Lots of chips were flying. One found its way under the glasses and into my cornea. Very painful. It left a "rust ring." in my cornea. Fortunately I got to the ER in a few hours so the ring wasn't super dark and didn't need "polishing out" later by the doctor.
Good tip on the WD40 for lubricant, looks like you got it matched up and blended back pretty nicely!
+🔥Ramsey Customs - turbocobra thanks
Agreed 100%. I haven't seemed to need the help much with my carbide burrs since I went with single cut rather than double cut. It's supposed to be better for aluminum. Seems to be true. They never clog up, but they haven't seen tons of use either. Buying the cheaper double cut burrs would buy a LOT of WD-40 to prevent galling. LOL
ATF works very well also.
I was watching this video, as I ported my Intake Manifold. I've been using hand Filers, pretty easy since mines Aluminum as well. Then smoothing it out with another filer. Great Video

I tried to subcribe to the channel and found out I was already subscribed. Its good to see you take the fear out of diy porting
Love the music. Great video. I'm porting a 351m Weiland 4 barrel intake this weekend. Thank you for the video.
Three is such a fun age! When my son was young, I would read to him at bedtime a book called My Race Car. He had it memorized. So I would improvise new lines or plot twists. He loved that. Now speaking of twists, I'm into a unique off-road build based upon a T5 swap into a Vanagon. Custom 4X4 "sin crow." Pretty soon I will start a build thread on TheSamba.
+Kevin Hornbuckle sounds very interesting
Well, we'll see. The idea is for my son to have a reliable and fast travel/camping rig. He is a trombonist in music school. During summers he can get good work in west coast music festivals between San Francisco and Bellingham.
Great video! Just a question, what is the best way to clean the runners for those aluminum bits and also for decarbonizing? Water and soap can do?
The MOST important thing in porting( as a porter) is get the right intake first! 2nd, have the right tools that works best for YOU, not someone else. I only use air tools to remove unwanted bulk. For the important part I use a FOREDOM foot controlled unit. They are expensive for the USA made Foredom but NO SHORTCUTS.Have a plan/theory. Don't cut metal just to cut metal. If you don't know what to do, just port match everything and leave it at that. You can always go back at a later date.
I have a background in Physics and have build engines that have set 14 land speed records, won AMA titles and put smiles on many a face!
One thing to remember, velocity is more important than volume!
true dat
Steve Solo who are you?
Your not al Teague are you ? And I'm being serious
He's gasket matching right
Your children are beutiful!!!!!!!!!
Get yourself a high quality variable speed electric die grinder. I've got an old corded quarter inch Milwaukee that I've had for around 40 years. I use it with a speed controller. It may be a little bit of an investment, but it's a tool that you will use all the time once you have it. Also, pick yourself up a good old can or tube of quality grinder grease. You can use the WD-40 to keep the residue down while you're working.
Now THAT was a really nicely balanced video. I usually enjoy a good porting video, but balancing it out with some questions and family time? That was a super hi-end quality choice to edit all that together.
thanks
Love the ending..! Awww.. God bless your beautiful family and the business.. Keep moving foward, Best of luck to yall. Thanks for the how to videos btw.
+yoed mirabal Thanks man
Nice job! I can appreciate your talents and experience. I’ve been around this and in the biz since childhood. I love the twist on your vid. (Those kids!) Beautiful. She’s definitely a “Daddy’s Girl”. And the little one is so content! lol! Take care and keep up the good work!
I grew up riding motorcycles also, And go carts, My first bike was a honda XR-75, I purchased it from a good friend of mine who raced that bike, when he upgraded in class, he sold me, his Honda XR-75 bike, it had many upgrades, and was very fun, and very fast little bike!
My first bike was an XR 75 also, great little bike, lots of fun!

just want to say you do some great work and a lot of people have no clue on how to be in two worlds at the same time thats the hobby and the family I have 4 children and 5 cars some of them are racecars and some of them are street cruisers love building cars for people and myself my day job is working on diesel engines on buses and a full time dad and im only 26 thanks for the tips and taking the time to read this
thanks for watching
This video was cool , had good music and adorable all at the same time 👍🏻
Nice vid im im doing a pi head swap on my ford, so any tips on how much hp ill get by porting the intake manifold and heads and will it be a good idea with my stock pi cam
I do basically the same and have done a number of heads and intakes. Electric high speed to rough everything in, regular ol' slow drill to finish/detail. Sit my ass down w/ some music just like you show...except I put hearing protection over the earbuds...kills my ears otherwise. I find there's a certain meditative quality to this kinda work.
yeah for sure
first I want to say I love your videos. sharing knowledge is how we all become better craftsman/woman. My set up for porting that I like is an electric die grinder and a simple foot pedal from Amazon. it allows me to control the speed, keep my hands free to control the machine and is safer than using the EDG with the on off switch. been porting heads for about 6 years now....
+D Rell (Duce) awesome...thanks
This is to me exactly why I love this channel. I knew porting a head was good for performance but I had no idea what it was how it was done or anything. In under 20min I now have a much better understanding of the whole process. So happy.🙌😁
this isn't porting... its gasket matching. this will increase throttle response maybe... but possibly lose low end torque lol probably barely increase in CFM
Good job bud! Your blessed with a beautiful family!! Lime to see you head porting and deshrouding the valves!!
Dude i STILL refer back to your tube bending video's!!! This is another good one
hey man very cool videos I have a set of gt40 heads just redid myself also picked up a cobra upper and lower would gasket matching the intake benefit me?
Too cool! I just bought a 67 stang with a stock 78 351 W. Was thinking about buying the edlebrock performer top end kit, but maybe I should just port & polish the stock heads & intake manifold?
If they are cast iron I would suggest just buying new aluminum ones...the cast iron is a pain to port
What gasket do i use for my edelbrock performer on iron eagle heads? there is a gap at the runners. Seems heads were milled before i got them.1970 350cu
I started out to do the same thing to my 350 small block. I'm using an Edelbrock intake manifold and Fel-Pro gaskets as my guide. The gaskets are much larger than the intake port. Like you, I would have to remove a great deal of material to get the intake manifold to match the gasket. When I put the same fel-pro gasket on my cylinder heads, the port shape of the gasket is much larger than the cylinder head opening. If I make the intake manifold port the same as the felpro, there will be a great deal of mismatch between the intake manifold and the cylinder head port. If, and when I bolt the manifold to the heads, the mismatch will be significant. What I'm wondering.... with all this mismatch between the manifold and head, won't the disruption of flow hurt the efficiency and performance? I think it will. Oh, I'm using AFR ported 180 cylinder heads with the 2.02 and 1.6 valves.
Rob Macfarlane Hey what's up just going through his comments for answers to some my questions and was wondering how did you make out and which of the 2 parts was larger than the other. You said mismatched but didn't specify which one was larger,smaller, and I would love to know the end result? Did you change the valves because of the problem or they stayed the same? Looking forward to your reply and if you have the time to can you write the details. Thanks and have a great day.
The intake runner should always be ported smaller than the gasket. Just make them equal and square them up. If the heads are ported right, there will be a taper into the port that will compensate for typical misalignment.
read sumtin about porting a while back that kindah made sense
the older tuners that tested there ported intakes for carburaters on the dyno kept the surface slightly rough
the roughness caused the air to roll around a little wish kept the fuel atoms suspended in the airstream
people that used polished intakes thought the air would had less resistance and flowed better , it did but allso caused the fuel to setle and puddle in the manifold wish caused the engine to stumble / bog down wish robbed power
with the newer portinjection manifolds they now tend to polish everything in front of the injectors and keep everything rough after the injectors , not sure if its the right way but it makes sense in getting the best of both theories
by the way good news for me : think i finaly found a bigger (shared) garage / storage for my trucks with use of a lift ,that its about a 1/2 hour drive from my home
hopefully it will help me finish the trucks i own
+watahyahknow I have heard very similar things about leaving cnc heads alone because the tool path marks work the same way you just described
Yep smooth intake ports are a bad thing all the new c&c stuff has little edges all the way down the intake port
I like to have the heads on the block torque the gaskets down, mark it all, undo it scribe the intake Glue gasket back on the head on the marks. After you cut the intake, tourqe it back down and check it with bore scope you will be happy. I used to do them without that until I found on some heads I was having overhang. They look good though.
I've been thinking about doing this to the 340 Dodge small block. I would use gasket material and a small ball peen hammer to make a template of the head. Then transfer that to the intake. With my luck the ports on the LD-340 intake are larger, and I'll have to grind down the cast iron heads. Great kids, your daughter cracked me up. She probably has a list of mods for you to do to her Jeep, before you can carry on with the goose.
that would work
0:34 music kicks in* thought I was watching a Ford commercial
Cute kids you have there and very helpful video I also don't have a air compressor big enough to run my air grinder too long, already have the carbide bits so that's a great idea I'm going to have to pick myself up a corded drill as well :-)
laughed my ass off when I saw you put that bit in the drill 10/10
I always taught you had to have some special skills which i didnt have to do this till i succesfully ported my first manifold.
Are you buying a new gasket with bigger holes and porting to increase the airflow or is a stock gasket holes typically bigger?
Does opening up intake port to match heads intake port size slow down the air velocity?
Yes.
What is the tune your listening to? I like it.
I found that if you use a scribe instead of a marker..it gives you a better shot of a closer and better cut match..hope it helps someone..
I would agree with that
everyone else says corded electric drills are not good for this. one said something about the sideways forces being bad on the bits. they say the rpms are too low. would you also use this on some iron heads?
I never had any issues...I would spend the time need to work cast iron heads
I’ve always stuck to using chalk to keep chips from clogging my grinding tools, but WD works just as well!!
Thought about doing this to my intake manifold during a rebuild, but what happens when you do all that work and have to replace the gasket later on only to find out the new gasket no longer matches the ports either...
if you port match to a known gasket size you just keep ordering those gaskets in the future. Felpro makes over sized gaskets for high performance use....also stocked at advanced
Awesome videos man do you live in SC?
Can I just port a head but keep the stock valves? Would there be a difference in power? How does polishing a head make power?
Can anyone tell me if this will help or make it worse if I open intake runners all the way open they have these little squares in the runners
as a combat veteran that song ya played while porting was outstanding.
Glad you like it
Getting ready to do mine great video keep up the good work hoorah
Curious how far into the runner you actually take the Porting? Just curious how large a benefit you can get by just porting near the basket flange and not addressing anything up top in the plenum.
+Brandon Wilson These runners were already nice, they just didnt match the head so in this video I was just matching them to the head.
Luv dah tunes bro...
Dude, nice...thanks for the knowledge
Thanks for the vid, keep em coming. Cute kids.
OK, I did the same thing to my GMC 5.7 with that worthless Throttled Body Injection system. I'm trying to get a few more ponies out of my TBI set-up. Here's what I did:
I match ported my throttle body injector set-up to my Edelbrock intake manifold. The TBI has two throats that are both cylindrical in shape. I bolted the manifold on to my Bridgeport and got the mating surface fairly flat. Then I bolted on the TBI, removed the butterflies, and dial indicated each of the two throat bores. I put this dimension on my digital read out so I can remove the TBI and still come back to it and get the centerline of each throat bored to line up with the spindle of the mill. The two tjhroat bores are perfectly lined up to be bored out to a larger throat bore diameter. Oh, I'm using the after market TBI set-up. This has the larger throat bores. They are bigger than stock. OK, here we go.
I start boring out the first throat bore. First, I'm into the l vacuum passage, and I've still go a long ways to go. So we keep going making the hole bigger. Next, we are into the water passage. Not to be discouraged, I still have about .150 more to take out of the hole. I figure I'll make some aluminum sleeves. OK, so we keep making the hole even bigger....to allow for the .100 wall thickness. OK< so I've got the sleeves made and the two throat bores ready for the sleeves to be pressed in. Probably some bondo to seal the sleeves is a good idea. So, we get all done. I take a skim fly cut on the top of the manifold to insure a good mating surface. Wait for the bondo to dry and install the manifold. Put every thing back together. Fire up the engine.........and there is no improvement at all. Nothing. No nothing. No improvement.
I'll check back after l change the cam shaft.
Rob Macfarlane does your TBI butfly open all the way out
damn, i guess there is absolutely no way to get the tbi's to perform right lol
If you buy the aftermarket TB from Holley, the P/ N 502-6, the TB comes with a gasket that's about a quarter of an inch thick. You need this thickness to raise the TB away from the manifold otherwise the butterflies with bump on the manifold and not open all the way.
dn-------The only thing I have not done, yet, is change the camshaft. The cam is the heart of the engine and controls how the engine performs. In my case, I've changed the cylinder heads to AFR 180 heads with 2.02 and 1.6 valves, added headers, and edelbrock intake.
I am experiencing very little HP increase. I expect the CS to make all the difference.....I hope.
Rob Macfarlane fine cop car with the TBI on early 93 they work every will
It's awesome you involve the kids. Keep it up!
thanks
for a nice final texture . try a wire wheel on a die grinder . also works super well to get rid of carbon build up in the runners. also this is only efficient if matched to head porting .
+twistymcslide2 I was matching in this video
+The Fab Forums you gasket matched to intake manifold ,, but its only matched if you match gasket to head as well . surprised theres so much slop room in the gaskets bolt holes. mad wiggle room .. makes it hard to keep consistent and or accurate when installing. def try the wire wheel on a dremel for final texture, but for aluminum, make sure to use a designated one , so no cross contamination happens . but it'll leave a final texture of about 2k paper. almost mirror like.
@@Thefabforums what is the name of the drill you use ?
Nice job match porting and a great Q and A
+huck01955 thanks
Just wondering ,improve performance much? Like without porting heads to? Cheers from Oz
You gonna kill power if you do it like this. You need to first make a mold of head openings and transfer that to intake manifold. You should never use gasket for this job.
Nice family. thank you for the info.
Once i port my manifold were do i ge my gasket? I have a b18 integra iwouldnt mind porting my intake to pull harder i guess iwanna try it out.
The the B20/VTEC engine should have a larger manifold and intake to count for the larger cylinder displacement. Most port jobs are smaller engines port matched to larger engines intakes/manifolds from the same manufactuer group, there's a good chace they match the same stud pattern on the engine too. Larger intake > ported smaller engine > Larger manifold
Instead of using WD40, you can get blocks of bees wax that works better and last longer. Works great for any aluminum work, even on sandpaper!
Nice shop bro!!!
Thanks for taking the time to make the video. Now I'm porting my own. Saves me some cash. Is it just as easy to port the throttle intake as well or is there to much meat for and electric? I have a 6.1 hemi
right on
hey,
i have a 351 windsor that has an aluminum intake manifold just like that one. the engine was rebuilt some time in the early 90s before i was born, and i don't know if the guy who owned it before me did a good job in rebuilding it.
A, because it has an aluminum intake manifold, and i don't know if they put them on there in the factory in 1979.
B, the last opening (what looks to be a channel for coolant) was closed, and it was opened on the heads.. plus they were clogged.
My engine was over heating for no reason. the water pump was good, the thermostat was out, and i had put brand new coolant in it.
so when i pulled the engine, i saw how the the end was blocjed off.
my question is, would that be the reason why it was over heating? does it need a new intake manifold? this is a real head scratcher. i never found out why it was over heating. and i still have no idea until today.
+Omar Mahmoud no most aftermarket intakes dont have a rear passage. If you didnt have a thermostat in it thats probably why it was over heating. When you remove a thermostat, the coolant is able to flow faster than it should and doesnt stay in the radiator long enough to be cooled down.
+The Fab Forums thank you sir, ill make sure to try it out.
hey man just want to say out of all of the videos your's have to be the best. I'm just starting my 04 mustang v6 build putting twin turbos on it. I'm new to the turbo thing but I want to try it. what do u think, hp wise thanks and keep them coming
Thanks Roy...no idea on HP. I dont have nay experience with v6 combos and even then it would really depend on a lot of other factors. Sound like a rad build though
Hopefully it will be, but on the real you are very talented love your builds and you talk like you really care about the job not like the others that just want ppl to see them
awesome job! and very cute kids!! nice dad - like al lot 👍🏼👍🏼
+YNK AMN thanks
excelente trabajo, lo maximo pasar tiempo con la familia. saludos y gracias por compartir.
+celso guajardo villarreal gracias
I think for this job it would have been better to use a cylindrical tree file instead of a oval since the oval one removes material inconsistently meanwhile the cylindrical one would be straight all the way through. . .
Does it really make a difference porting the intake?
Nice channel. Grew up in Lexington. Plenty of hot rods there.
do you know where i can buy a manifold for nissan micra for carburetor intake manifold?
I dont sorry
cause i want to convert my nissan micra k11 to carburetor.thats why i need to take new intake manifol for caburetor.
try STILLEN in Orange County, Ca. If they can't help, they can probubly tell you who can.
You are a a good man keep up the good work
+Ryan Roman thanks
dumb question the bibster is the fox buggy right?
+Noah W (BmxNoob) yeah
Nice work!
+Blake's Garage thanks
Kyle Love your stuff. but one problem with a drill is the rpm it's to low for the carbide tip. it tends to chip small pieces from the teeth. because of the wrong cutting speed. they're made for die grinders with a rpm around 20.000.
the carbide tips last much longer. sorry about my English. from Sweden.
+Victor Bergdahl Thanks Victor. I have been using the same bits and drill to port with for over 10 years now with no chips yet.
Good tip about the WD-40 I could have used that a few time in the past. No tool box is complete without some WD.
+Tim datoolman for sure
Nice job. Cute kids.

The Fab Forums
The Fab Forums Will ported intake manifolds work with the stock non ported cylinder heads or do I have to port the cylinder heads as well?
Elisabetta Canalis It will work. You don't have to port the cylinder head. BUT if you have things apart and have the time you might as well port the intake and heads. You will get gains from the intake porting but of course if you don't do the heads it will be choked down a bit. Imagine going down a nice smooth slide. Then near the bottom the slide narrows and there is gravel scattered about on it. So your gunna be slowed down a bit i.e just like the air going from your ported intake runners down into the unported heads.
R. Flash Thanks for the info
Not a Ford guy, but beautiful family and awesome porting vid. I'm out in California still. Good day.
thanks
Good job awesome video
Like Turbo ducting in back ground. Do you you have finished ??
+Mattric k yeah its done
I wanna do this on my subaru do you think it will work? will I notice a power increase? do I need a tune after?
Probably wont notice much of a difference. This is more for matching an intake to an already set of ported cylinder heads.
awesome video. Where can I purchase the carbide bits? Porting 5.7 heads
I think I have some links in the description of the video
Love the quality of post production
+TheRainbowPastries Thanks

thanks man
What's the amp of your drill? I'm going to buy a new one, and want to. Make sure
it's strong enough like yours.
cant wait for an offroad build on the fab forums channel !
I have the itch
i watch your channel all the time, but i am really into the custom jeep cherokee XJ's and chevy square body trucks such as k10,k20,,k5...i bet any offroad build you do would be spectacular! besides dont you live near a shit load of public offroad trail systems.?.!. they have closed all the trails here in western part of nc, but i still continue to have the desire to create custom trucks,buggies, and jeeps
FYI,,, gasket matching provides very little (if any) gain! (unless the head has a smaller opening than the manifold, then it's worth doing. Opening that up, can hurt more than help b/c the air slows down when it hits that larger cross section.
Just saying... Always enjoy your videos though. Rock on.
MCE Performance
Yeah for me its not so much about performance....and more about doing it right
have u ever powder coated the inside of the intake makes it smooth as glass keep up the videos
+Electrical_Dynamo I have not
I'm surprised your son was so chill when you had your phone out lol my baby boy goes crazy trying to get my phone when I have it out
yeah he was pretty young then
