Thanks. Just trying to compute compression ratio.

What compression are you shooting for? With flat top pistons you will be lucky to get 9:1. I have cut the heads as much as .060 and gotten them down to about 75cc. That would be ok for a street engine but it gets dicey getting head gaskets to hold if you get up above 10.5 compression
