I just want to say Thank You to all that gave their advice. One other thought what would happen if I used my 73 340 heads ? Should I shave them or leave stock?
I usually mill heads, like said above. Just did a set of 70-71 J heads. Had them milled .020 and .019 on the intake side. 73 heads are good, should have hard exhaust seats and decent flow. I have not cc'd 73 heads but should be the same, about 69 cc per chamber with the .020 cut.
