So far I've mad the plans to add the folllowing to my stock engine. Headers ( Any recommendations? I think I'm going to try and save up for Thorley's or Hookers) Vortec Heads? (Good upgrade or should I look for other heads?) Edelbrock Performer Vortec Manifold Injector spacer Adjustable fuel pressure regulator High volume fuel pump Am I missing something? Should I drop something for something else? Also, I'm going to try and clean the fuel injectors soon. Will that give me a noticeable gain in performance?
