Since it's together I broke out my new deck bridge and measured the pistons at a consistent. 020 down in the hole. In an effort to maximize my available compression I guess I'll get .027 thick Cometic gaskets but I don't know how to choose the bore size of the gasket. My brain says it should be as small as possible as long as it's bigger than the 4.030 block bore size. Is that correct?
