Actually, it's alot. Alot of machinests I talk to cannot afford to do that for customers. Major shops and companies can afford that because they can afford CNC machines to duplicate flow numbers. You can do some at home tricks, but for the most part, its a guessing game, that's why people hesitate to port their own heads, because if the flows aren't duplicated, you can do more bad then good.
