I’ve ran a lot of blocks that weren’t squared or cut for a long long time. Each and every combo was in the hole. I hear the word quench thrown around a lot but in the case of my sons 360. The pistons were flat tops well in the hole, felpro 1008 head gasket, open chamber 340 style Edelbrock heads, and it ran 10.30’s@3200 pounds. So I guess sometimes something that shouldn’t work by the book, works. Would I lose sleep over .012????? Hell no.
