kcress... in my opinion, unless you're racing in a compression restricted class, cc'ing is a waste of time.

Shawn, the guys pretty much covered everything I was going to say... keep the intakes a lil rough. We get $30k, 775-800 hp, 9000rpm 350's and 380's and the intake ports are by no means mirror smooth. Gasket matching is definitely a good thing. Pay attention to the bowl areas, much can be gained there.

Also, whatever tools you use on iron heads, make sure you don't use on aluminum heads... you can embed iron into the aluminum, which can cause galvanic corrosion and lead to gasket leaks.
