Hey I dont know alot about them but my engine builder (Automotive Specialist in Concord NC) swears by them. He's tried the afr's and the trick flows and he says he can get better flow numbers across the complete lift out of the RHS heads and says he can make a good bit more power out of them. There are not alot of people that know about RHS heads but my guys think that its just a better casting than the others and they are less expensive. j
