Not saying good or bad, but i saw that Murrey, is advertizing them on his all alum 632" street motor for $10,000.00 and his blown 540" street motor. Quiet a few people here on RJ, had good things to say about him a few months ago. With that being said i'm a ProComp dealer but donot advertize (anywhere) I never buy a set of heads assembled for a customer, and always recommend that they have a rep. machine shop assy them, someone that can check the seats, and the valves for runout. I also donot sell them for racing only street motors.
