Blowdart, don't waste your money on a solid roller unless you're gonna get heads that can really use them. A good flat tappet cam will open the valves very quickly. Put a Clay Smith solid flat tappet cam and lifters in it with some hughes engines roller rockers and manton pushrods. You will still need to change springs and setup the heads and possibly your piston valve reliefs for this. I'm talking somewhere around .530" lift/290 degrees adv duration.
You can call George at Clay Smith cams and talk to him personally. He's been doing this for a long time, and he can tell you what cam will be best for ya.
