You might call Mustang Specialties in Pompano Beach. The work almost exclusively on ford motors and do a lot of high performance builds and modifications. John is the "carb guy" as a lot of them work on EFI only. But they have a head porting shop and should be able to do what you want - or they can certainly give you a very informed opinion on who can. They dyno tuned my 331 stroker and at the time they had 4 cars in the shop being modified - 2 late model "hot" mustangs that they had changed heads & cams on (something like 550 hp and 700 hp), a Fox body Mustang that was a dragster (chute and all) and a 'tamer' stang with some engine mods.
