Well, contact the head porter and ask questions. That’s where you start with the heads. I called today for a crank I have that needs to be addressed. Dropping that puppy off on Monday.
That’s why I pointed him toward Rod and Vic. They can cnc a set way faster than I can hand port a set. I’ve never seen a set being done but I’m guessing you set up the program, bolt the head down, and go do something else while it does its thing.
