those heads are used? how did they turn out for you? i heard even used with cracks they still do not effect performance in anyway. In fact i heard from the factory they had cracks while being made?
Yes used from a 5.2 engine core. Passed a pressure check, have been milled and are getting new springs to run on a .030 + 5.9 using an LA rotating assembly with a 380hp crate engine cam.
Hoping to make 4500 horse power on vinegar and dish soap mix.
