How much did you take off? What is your compression ratio? Chamber volume?

As it stands right now, if I bolt my Stealths on my 383 (.030 over, slug .035 in the hole) I'm at 8.8:1. This is basically a stock spec street motor with a .450 lift cam; very mild. I got the Stealths becasue of their affordability and close resemblance to a stock casting more so than their added performance. I'm just wondering if I should mill them or run them as is.
