Heads/intake ports
One of my customers works for a machine shop as a head rebuilder. When he told me what he did i told him i was interested in porting my heads and intakes. He saidthey don't normally do work like that but that he could do it. He asked me how much porting i wouldneed and if i neededa valve job to go along with it? I didn't know now how to answer him. So my question is , are there particular demensions when it comes to porting? do the valves have to be reworked too? help.
