Whoa whoa WHOA. I never gave Procomp or Speedmaster good reviews. I never even had a set in my hands (and NEVER will) ProMAXX yes I have in in my hands and on my Flowbench and from what I've seen, I LIKE. They are 10 times nicer than Edelbrock heads and after talking to Mark at ProMaxx I would buy a set tomorrow over an Edelbrock heads if I needed a set. But I don't. I will never buy a procomp now called Speedmaster head. I would continue to FIX Edelbrock heads if it came to that. I can do them in my sleep. LOL
