It is not that common to bush the lifter bores on a SBM, some say you should but I never have. I actually just sold a set of lifter bushings that were on my parts shelf for at least 2 years. Hughes roller lifters I know nothing about. The solid roller lifters I have are made to Brians specs, the oiling is different and everything, not like an off the shelf rocker would be like. The Harland sharp rockers for a SBM from what I have seen and heard are way off on the geometry, they do better with the big block rockers. I am sure if my block needed to have the lifter bores corrected Brian would have said something about it since he did all the machining and assembled the bottom end. He did line hone the mains and the cam journals, I can also see that he honed the lifter bores. This engine spins very nice and smooth for sure. We will see soon what it puts out.
