What is your CR going to be?
I don't know what your heads CC at,but I would guess around 75 cc's.
400,.030" over,10 cc piston relief,.040" gasket,block zero decked,I'm showing around 9.8:1,that would be good for the 60916,might be getting close to detonation with the 60242,but Ken would know more about this than me. I would rather run the 60916 myself.
