blown 2 head gaskets

I don't want to belittle or bash anyone.........BUTTT

Come on you can't run a 1008 if the O-ring in the block diameter is not larger than the one in the gaskets. If you plan an O-ring job and do it with the intention of using the 1008 that is fine. But, 99 times out of 100 that wire aint in the right place. A properly done O-ring job will not have gaps. A good installer will put them in where the best eyes can't find the ends.

Surely you do not expect a stock replacement gasket to hold the compression you are running along with 150HP nitrous. It just don't work. There might be a rare case but, come on.

Call Clark or SCE and order some copper gaskets. Get some copper coat from the parts store. Clean the gaskets with a paint grade solvent. Hang em up. Spray a light tack coat. Then spray another coat of the copper on them. Figure out how they go on the engine then carfully lay them on the block and start putting that puppy together. Get the heads bolted and torqued down as soon as possible. With copper and O-rings done properly you can push the mains out of the block before that gasket will fail.
