Thanks for the info. The thing with solid rollers is that I haven't seen any solid roller lifters with pushrod oiling, which I need since I'm running magnum heads. I might break down and take it to Brian, even though I really can't afford it, which is why I'm trying to do it myself. As for the flow numbers, a lot of people are skeptical of the numbers that Hughes claims for the work I have done on mine. I won't change the heads because I have too much into them. I know there are better choices, but they are what I have, so I'm sticking with them. I've heard lots of good things about Engle cams, but haven't heard of Jones. Is that the one you were telling me about the other night?
