Purdy:
I am using aftermarket racing studs that are slightly longer than the originals. I believe they are the length of the one that is supposed to have the ignition wire clamp on it. The copper gasket is .031 thick. I don't remember exactly but I think the pistons were up about .117 above the block. They were all right with the stock head but not with the 7:1 head. These heads are not under cut like a stock head.
