found this from Jason at DieselNut

Cometic has a pretty cool Gasket out, and it can be had with a Oring build in it. No need to machine anything. You do have to make sure the head and the block are flat, no waves or anything. These are MLS gaskets similar to the units on the CR trucks. I would sugest trying one of those along with some 12mm studs and I think that will work fine, as long as you don't have some crazy twins set up or something, but you will have to find more fuel before getting that kind of boost.

Is your gasket blown currently?

not worried about driving it now.. i forget till it happens.. actually i just now realized that they all happened on friday..

the thing that pisses me off is once its had a heat cycle or 2 though it the thing will hold 60 psi.. but if u even touch the pedal without a warmup of at least 5 mins.. even if u dont build any boost.. it will still blow..
