and they found that factory rockers are way off on the face/rocker tip. He's been offering a set that he trues up. That rocker tip being off side to side probably puts a lot of pressures were they don't belong!

I don't doubt he's finding some things but here's a pic of a trunion shaft out of an engine with 4,500 miles on it. If the rocker were severely tilted you would see damage close to center on one bearing surface and the other bearing surface would be damaged out near the retaining clip. In the pic the one side is damaged worse than the other but both sides are damaged near the center of the shaft.
