Head gasket choice?

[1 RARE T]

Popped a h/g at the track and am going to change them both.

Had Fel-pro 944 in it but should I put them back or go with the 1000's.

Did a search but did'nt get a definate answer.

Running Alky at 24psi.

C-16 at 25psi. at the track.

Stock heads

I used the stock GM gaskets. A good friend of mine uses stock GM gaskets in his 10 sec turbo T without any problems. If you can tune the knock out you will be in good shape. If you do get severe knock I guess it is better to replace a head gasket than a crank..piston...rod. They are sort of a safety valve

I agree. I use GM head gaskets as well. They've been on the car for a little over two years & never replaced. See times in sig...

With a stock bottom end, go with stock or felpro. With a studded and steel capped bottom end, go with Cometic HG's and be done with it.

Go with the GM's or the fel-pro 9441's. As stated better to replace a head gasket than a crank. Stay of the knock!! Frank

I've been through this as well and tried the 1000's after running the stock composite style the last two times. My experiences with the 1000's was horible. I blew one on a fresh rebuild at 15psi. Detonation was little while sorting out the tune, but nonetheless blew the drivers side. I had replaced the bolts for studs hoping that would help, but no such luck. I replaced the drivers side and not more than a week later blew the other side with C16 at the track and 20psi no detonation. I don't know if it was a bad pair of gaskets or what, but I'll never use the 1000's again. I replaced them both with a single steel shim coated with GE1000 construction adhesive (the stuff RJC sells). I've not had a problem since and have pushed it much harder than ever before with the 1000's. The stock composite or steels from my experiences have worked very well. Just my .02.
