Here is my take. If you are more then capable, you should also be properly equipped. As for your mild measurements, if you really were capable you would know what the differences should be. That said I think you should HOLD OFF. I'm not saying don't do it, but you need to do ALOT MORE RESEARCH first. The way you asked makes me automatically think you aren't educated enough to tackle this yet. Can you grind here and there and get better then stock results? Sure. But that doesn't mean that it's the right thing to do. Figure out every term associated with port work and if you don't know what they all mean and do, you aren't ready. ("Pilot holes")
Give it some time, research the subject thoroughly. Then tackle it with an open mind and expect the possibility that something will go wrong. That way there aren't any surprises.
