ALERT!! SOUND THE ALARM!!..

I saw what jpar ordered. He’s fine. The smaller the bore in the gasket without hanging in the bore the better off you are. Crevice volume increases for no reason suck.

Also, the top of the piston is under nominal bore size, so even though he is .010 out of the deck he’s just fine.


When you order them from 4secondsflat he recommends .030 over the bore size.
