Man I gotta raise what I charge to port intakes

Plus trust. In my case people are sending their stuff to a 33 year Millwright that taught himself how to do some porting work. Who in their right mind would sent parts that they bought with their hard earned money to a Millwright. Lol. You would have to be half crazy.

From what I understand porting is something that can easily get to the point where the head is ruined. I suppose if I were to have it done, I'd want a guy with a flow bench to give me a before and after report. How guys do it at home without knowing or guessing seems ridiculous to me.
