Paul C at Carter Racing may be one place to check. He may or may not be porting iron heads.

Another one that was part of an engine build I got involved in is Dan Barton. He ported a set of 72 455HO heads that I had Paul C rebuild and flow test. The port work on those were excellent. Don't know if Dan is still porting iron heads these days or not.

Iron has seemed to fall out of favor with most head porters when you have a market flooded with aluminum offerings these days.
