Craig Hendrickson and Kern Osterstock published a couple of books that were available through H-O Racing Specialties, one of which was "Pontiac High Performance Engine Design & Blueprint Assembly". It had a section, with illustrations, on porting Pontiac heads. Very informative reading. I had to replace my origional copies and found both this and their "Pontiac Heavy Duty Parts & Specs" at one of the book clubs, but if all else fails, I see Craig post on the PY forums website, once in a while.
