Brett Miller has a CNC program he is working on. They are beautiful. The heads he hand ported made 940 on a 400+ inch nitrous motor without nitrous. Brian at IMM has a customer who also runs nitrous and his motor makes great power (I forget how much exactly) but it was impressive. I bought mine because they were cheap. They are at IMM getting flowed now.
I'd have to see the heads to make a really educated opinion but ANY Brodix BIBA stuff I just don't think will support that kind of steam--but then again "Where there's a will there's a way" J.Rob
