You could hit to deeply and grind through into a coolant passage and your heads are done. You have to know how a head works to make it better. Enlarging a port is just a small part of the work. You have to know how to increase velocity not increase the amount of air flow. There are at least 15 different measurements into consideration just to guaruntee similarities and have the heads flow evenly.I wouldn't even touch a set of heads. That is why I have pro's port heads.</blockquote>
