If I’m putting new valves in my head and using original valve seats and guides. would it seal up good without grinding? As long as Seats and guides are in good shape. I’m just curious it’s my first time rebuilding a engine. It’s a 95 tbi 5.7 with vortec heads and an edelebeock avs2 4bbl.
That's not valve "grinding", it's valve LAPPING. Grinding is a completely different process, used to angle the sealing surfaces and backside of the valve. Lapping is just to make sure each valve seals to its seat.
I have a 1995 k1500, the year before the vortec heads, and a 1996 c1500 as a parts truck with a 305 5.0 vortec. I have rebuilt my 1995 but the difference between the two motors is really very little
Jacoby Noctis The TBI heads didn’t breathe as well as the Vortec heads but the TBI heads were much more durable and didn’t have the notorious cracking issues. I have a 1995 K2500 TBI . More durable and easier to service compared to the 96-up Vortec.
I almost dropped one of those keepers down the oil port. Once changing seals head on. Talk about being scared lol.
+barry cowan Thanks for checking us out and taking the time to comment! 1AAuto.com
Now that's scary
What is a good solution to clean carbon?????
very nice video as I'm learning about engines
+Christie Turner Thanks for watching. We hope you continue with learning about not only engines, but vehicles all around with the assistance of our videos. If any of our viewers needs to make this repair, we carry the auto repair part shown in this video on our website. Here is a link to them www.1aauto.com/head-gasket-set/i/1aegs00237?CZcams&CTA+Comment&WeQHeQQP6s
So do you just torq the rockers down and your done or do you need to ajust eash one ?
U need to adjust the lash.the 4.3 vortec u can just bolt n go
just got my truck outta the shop said I'm running about 30 psi cylinder 8, he said this is one of the things I can do to fix it ?
no o-rings? are they optional? also are same seals as good as different ones for intake and exhaust? I have a new all-same kit..
Did you get an answer about the o rings?
you didnt show how to actually rebuild the head though. you just showed us how to take the valves out and put them back in. rebuilding the head requires new valve guides and seals which you didnt cover in this video. you should change the title because i just watched most of this video to get an idea of what i need to do, but turns out i have wasted my time watching this video because it does not show you how to actually rebuild the head.
No small rubber o ring on stem before keepers?
Same thing I was just wondering
Not on the vortec heads.
Is this the same as a 305?
So I can use a wire brush, on the gasket area of the heads?
+SavageLyfe As long as it's not aluminum. Sandpaper, razor blades, and a vacuum are commonly used. Just make sure not to scrape away any metal from the cylinder heads
How do you press a rocker arms stud stud on a 350 chevy
Just get a 10 lb sledgehammer and beat it in
@@jamesbarnes7045 i prefer fabricating a battering ram and then weld it to the front of my car, then i line up the rocker arm stud on the head and have my gf hold it in place. then i get in my car and drive at 160 mph and ram the stud. works every time
Same for 92 Buick Roadmaster 5.7?
No O rings on the valve stem before spring retainer?
I've noticed after market heads and vortec heads such as these only have the Umbrella seals per valve myself
The vortec valves do not have the oring seal or valve rotator.
Where can I buy the paint
Can you please do a video on replacing a 5.3 head gasket
+hardog22 We currently do not have an auto repair video that covers this particular repair. We will keep this request in mind in the event that we need to make this repair in the future. 1aauto.com
You warn the viewer to use a magnet to remove the valve retainers because fingers could be damaged if the spring compressor fails.... yet you simply use fingers to re-fit the retainers!!! Otherwise, nice video!
**Adds magnet wand to cart
Thanks a lot for the great video.
Will this be an identical rebuild for 1996 c/k 2500 5.7??

What cleaner did you use for the valves
+Kolton's Atv madness We used mineral sprits for the valves.
Nice.
Great video!
Didnt even check valve guides. A proper rebuild they would have replaced the valves, springs and had the head pressure test and machined.
Beehive springs
Beehive sprins are only necessary if running a higher lift cam with vortec heads. They're completely unnecessary with a reasonable cam.
I've never understood painting heads or any engine parts... Looks tacky
easier to keep clean and identify leaks.....plus it looks nice.
Khris Shultz cast iron will rust hence the need for paint. That being said , I’d paint them black cause Chevy Orange is ugly as it gets.
I'll just base coat clear coat
Rust protection is desirable on iron made heads, plus you get to choose your fav color. I did mine in sky blue. It is delightfully tacky, LOL
@@Meantime5 Isn't sky blue the color GM used in the 50's?
Chevy orange is disgusting I painted my block orange then decided I couldn’t stand it and blacked it all out
Aren't you Special !
@@Snailmailtrucker Chevy orange is definitely ugly as a bitch
That's not even chevy orange. Chevy orange has more red in it, like a burnt orange color. Not piss orange.
