Do you machine the block for zero deck.
the low compression 440 piston will set at .008 or so bellow deck in a factory block
Doesn't take much to get it above deck for more compression

No, they're budget engines I'll sell, I shoot for about 9.7 CR with whatever iron heads I use for it. I have about 10 engines to finish and sell.
