I have a 400whp gsr. Its gone through two headgaskets now. The first one was just the cometic gasket, no copper spray. That lasted for about 4 months. My second one witch is also the cometic I copper sprayed this one lasted for about the same amount of time. I cant keep going through headgaskets.

Whats the best headgasket?
Copper spray or no?

OEM.

Yes, that's a period.

I use OEM , make sure your afr's are correct and that you are not running too much timing.

Beat me to it. OEM only, and if you're blowing a lot of headgaskets you are probably having light detonation problems.

Contact Golden Eagle, like stated above.

It seems like everyone is saying OEM. But my tunner says commetic. He is a verry respectable guy in the area. I dont know why this is.

Why would anyone use commetic if OEM is better?

For you guys using the OEM,
How much horsepower is you car making?
How long has the gasket lasted, so far?

only thing I would ever run is OEM

Im using a cometic one...just make sure head and block are machined flat before putting one on

boostedteg4dr

For you guys using the OEM, or commetic. List the headgasket your using and
How much horsepower is you car making?
How long has the gasket lasted, so far?

About 570whp and the gasket has lasted about 40 1/4 mile passes and 20~30 dyno passes. I've always used OEM/Golden Eagle headgaskets in my motors, they were never an issue.

Maybe your tuner is a Cometic dealer? I'm sure as long as the head and block are prepped right, you will be fine with either gasket.
