Stock 318 building with Justin

047
piston .020 out?
Pistons are down .057
Heads are 72 cc. I'm milling them .047 if I use that cam. I'm thinking about a grind with an earlier closing would be better. After the conversation I had today with the grinder... let's just say I'm not impressed.
Side note is these 163/593 have the same 273 casting intake port that people "say" is best. You barely have to touch the short turn, just bowl and gasket match. Might not even do the guide profiling. I'll post pics as I go tomorrow. I have fk ton of stuff to do like ship some heads out east and get 2 motors together for this weekend.
