There was something different about the '86 heads or pistons??? that made them tough to do much to.. if I were you, I'd pick up a later 87-93 head cheap or spend a little extra and get some GT40s or have a port and polish done. I'm not sure how aggressive you can get with the cam but i'm sure that crane or even summitt racing tech would be able to tell you
