Head Gasket Selection?

What kind of head gaskets would you all use for O-Ringed LT4 Heads, running about 10-11psi with 9.3:1? Thanks Guys...

Any suggestions where to get them; I just blew a head gasket a few weeks ago and was going to spend the holidays working on them?! Did you get them directly from cometic?

I think I got them threw A distributor. I cant remember where BUT they are AWESOME! You can get them in different Thicknesses and from what the Builder's that I spoke with said they were SUPPER strong and could hold UP to Crazy boost levels! I was told there was practically NO reason to Oring blocks anymore now that they came out with these! Good Luck, Lata, Ark

Don't use Cometics if you have o-rings. You need a stock type gasket with a steel firing ring around the cylinder to mate to the o-ring.

If you've already got the heads cut, I'd just run a copper gasket. Are you going to machine a receiver groove in the deck too? Really though, o-ringing @ 10# is overkill. 20#, I can understand.

I'll be switching to Cometic. If you haven't had the heads machined yet, that's what I'd suggest.
