I had read all the info out there on them trying to figure out what mine were, and ended up CC'ing them. Glad I did.

Well with 12:1 you should use head studs and composite gaskets... imo. Stock o/c W2's should spec out somewhere around 70cc. Personally I would have gone with closed chamber and D-dish pistons.
