99 PI Heads

well you really would not have to buy pi cams if they did not come with the heads. 90% sold come with cams. If you get 99-00 mustang gt pi heads you would need new valve covers and a few new bolts for the timing cover. Also 99-00 pi cams have pressed on cam gears, so if you want to swap out the cams later on you would need them too.:nice:
