    Rated 4 out of 5 by from So far, so good.... I bought these to replace a pair of junk Procomp PC3001 heads. These are heavier castings and the springs/valves are better quality. The only issue is that one of the heads had one of the valve cover bolts holes drilled off center. It still works with my valve covers. For the money, these are a great head.
