I have a copy of the original flow sheet from these heads (see below). These are hand ported heads and have a sweet port job on them. They're better than any CNC port work I've ever seen, and the mid-lift flow #'s are incredible. They have approx. 3000 miles on them, and were cleaned up and resurfaced after being removed. They are ready to bolt-on and go.
