Review on Competition Cams 16058 Rocker Arm by Timothy Harper

I recently purchased a set of rocker arms for my automotive engine... Through trial and error, I found that they didn't provide any noticeable improvement in performance. The installation was also a hassle and required multiple adjustments before getting them to work properly. The pros of this product are that they are made with durable materials, however, the cons far outweigh this. Save yourself the money and stick with your stock rocker arms..
