Yeah, I had a brain fart when I mentioned the heads...it was kind of a last second after thought... But what you could do is take your heads to a local machine shop and have them cleaned up--have them mill the heads flat (.005) and then have them just polish up the CC, do a 3-angle valve job, and have them fully balance your valvetrain. That would put you at about a Stage 1.5 stock head...I guess. And when machine shops ''clean up'' the heads, they don't port them at all--just polish them and make sure everything is straight and true...there isn't a lowering of CR since they don't port anything--just better flow. And they look SO pretty when cleaned up!
