Cometic makes custom thickness head gaskets. I had to order a set of .057" gaskets for our 386 in our race car, because I had .022" POSITIVE deck clearance. Cometic gaskets are also reuseable. The machine shop I deal with have been replacing conventional wire ring arrangements on forced induction cars with regular Cometics, and have had excellent results. They are a little pricey. We paid $140 for the set for the 386.

I'm running a felpro 1074 (.039) on flat-tops in a 383 with a +.002 deck. It works out to be right at 12.45ish on compression, and I have no troubles. Just set your up for mid to high 11's on the compression, and tune it into submission Makes for a fun and snappy combination on the street IMHO. (and yes, I run it on local crappy pump gas - 91 to 93 oct). Don't be afraid of compression on these motors man. The computer is an awsome advantage when done setup correctly.

Re: Who makes thicker head Gasket!
Just wanted to add this. While I was building the 386, the heads were torqued down, and then removed twice before it ever left the engine stand...With the same Cometic gaskets. The car now has over 40 runs on it, and runs 10.90's. I'll never use anything but Cometic in anything else I build.
