Heres a good start for you. Joe Mondello was the head porting guru for Olds for a long time.

If you really dig on an internet search you may find some good info. Porting isnt hard. You need a steady hand and lots of patience. Let the right tools do the work,dont force it and walk away when your tired.

Taking metal away in the right area is key. It's the reason good porters dont share that info,as it's the result of countless hours spent porting and flow benching.

If you have a known "good" set of ports or heads to copy thats the best way to learn.I lucked out when buying the last set.They have a cnc ported exhaust and intake I can copy over to the other ports.
