I have a 350 engine (bored .030) with a crane energizer cam .454/.454 272/272 hydraulic flat tappet, edelbrock intake (performer rpm) and Holley 670 street avenger carb. I have stock heads with stock rocker arms. If I want to put full roller rockers on, just what exactly will I have to do. Will I have to take my heads to the machine shop or is there anything else I can do.
Any input is greatly appreciated
