You don't understand the things you suggested about porting (smoothing) anything.... there's more to it. CSA, venturi size relative to valve job and valve diameter, velocity in fps, velocity distribution, and friction which accounts for roughly 1% of cfm potential.
While I continue to learn and read, I've had my 18 months worth of machining, engine building, theory, design, porting, etc. 30K later with a 4.0. Start asking questions instead of answering them incorrectly. If you want, get a $120 subscription to Race Engine Technology by professor Blair. For free, you can log onto the Speed Talk forums where a lot of leaders in the industry of motorsports have intelligent conversation.
I get annoyed at babbling about things you don't understand well.
