429 problems

I put together a 73 429 with kb .30 pistons. And 68 c8ve heads. With screw in studs and guide plates. I can't get it to run very good. It ran better with the worn out 73 heads. I don't know if I hate the wrong ratio rockers or wrong length pushrods. Sounds good at an idle but once you put a load on it. It has barely any power

Maybe other timing problems? Vacuum advance not working? Go down the forum page and check out the forum on 385 series engines, maybe someone will know more.
