When I got my current cam I did clay impressions and took them to the machine shop. I told them I wanted enough cut to run a .600 lift cam someday if I decided to do that. They cut the heck out of my pistons and also cut the arc's of the cuts way too wide. I should have made them buy me new pistons but I didn't.
If I have the piston to valve clearance and I should but I will check it anyway, I'm going to try for a .070 angle mill on my heads. Spec's say they have enough margin for a total of a .175 angle mill. .070 will get me 10 cc's back and put my compression back up in the 10.5 range where my cam wants it. This should wake my engine up quite a bit.
The only down side I can see is if I were ever to go to a stroker I would have too much compression but then these heads wouldn't handle a 7000 rpm 331 so I'd be looking at new heads anyway. Am I missing something that would cause some catastrophe if I do this?
