Hi guys and girls, just wondering what people are using in there smallblocks with indy heads and a solid roller with over .600 thou lift? I had howads cam and lifters but i had a noise like loose rockers, found that the lifters have elongated the cup in the top of the lifter, so i was thinking to try the mrl ones but would love some other opinions, possibly guys that have used them, with indy heads, as the offset rockers and big spring pressures seems to be the problem.
