Default Head Gasket

Well, the car is in the shop today for what i think is a blown headgasket and hopefully nothing more....its a a Chevy Dealership in which i know a few of the guys there who drag race up in NY...

My question is, is there a better head gasket i should use other then the stock one if in fact i need a new one? Something that is stronger?

Cometic brand gaskets are what almost all the late model forced induction guys run. 5.0's, Ls1's, etc... I'm sure they make a gasket for your application.

yeah, they do, I run them on my LT1. Just make sure that the head gasket didn't go because of detonation. Otherwise the head gasket stops becomming the weak link and you start breaking expensive parts.

I agree, cometics are great gaskets for a blown application. However attention to block prepartation is important. Be sure that block surface is very clean. Cometic even recommends that one uses a sanding block loaded with 180 grit to clean up the top deck and the heads. This ensures a good gasket mating surface. Check out cometics website for more information.

If I remember right, you are running stock compression. Get the thickest Cometic head gasket made for your application. It will help reduce the compression, and hopefully help to avoid another blown head gasket.

Could it be that only at high cylender pressures something becomes seperated and such? Does the coolant tank still boil over when you are on hard throttle?

a puff of white smoke will usually indicate coolant, are you still getting the smoke?

gotta start thinking outside the box, from a clear perspective. Start back with the basics and work up from there.

Well, I'd also take the bill back to the dealership and ask for a refund or something.

Guess its time to go with the cometics. If you're still running stock compression I'd also say get the thick ones. Good luck, and I hope you aren't taking it to the dealer to get it fixed.
