Thanks, thats what I needed to know. So double check my math, I need to remove about .030 to keep them roughly the same size?

Early 5.7 85 CC
Eagle 5.7 67 CC
SRT 6.1 73 CC
6.2 and 6.4 73 CC

Is it OK to take off .030 on my BGE heads?

I am not causing global warming, I am just trying to hold off a impending Ice Age!
