Billy do you know who has the CNC program for these heads? I would assume that they are the same as a procomp head which my local machine shop has sold piles of and has had no issues. [/quote]

Marty,
This is the part that is so aggravating. Dr. J, Bryce Mulvey, was the guy who made the 220 CNC program. After he went through a divorce, lost his business, and screwed over a bunch of people, (I think he now works at CP pistons) no one attempted to buy the program. The Procomp heads are 171cc as cast, and there is a 191cc CNC port available, but nothing close to what Bryce was doing

If you ever hear of a set for sale let me know, I’m starting a 340 stroker build for my purple beater for the next time we do Drag Week. The goal is to run 10”s n/a ... we have some of the promax heads at the local machine shop that I want to get flowed and see how they do.
