well i havent done anything besides bolt-ons and im thinking about putting a cam in toards the end of summer. i'm going to stick with stock heads but i'm going to do 1.6rr and was leaning toards a cc306 cam. i have a M6 and 3.42's. i've got ram air and jethot longtubes. 3" side exhaust. i mostly drive the car on the street and i dont have to do emissions. my car shifts at 6200 i think. (stock)

will i be safe is i do the cc306 and 1.6rr and have my pcm programmed? is there anything i can do to my heads without spending a ton?
