I'm not sure why I looked at the engine this afternoon because I'm still waiting for my guide plates to arrive, but something looked off to me as I was looking over the rocker arms. I'm no expert, but don't rocker arms use studs with adjusting nuts? The rocker arms on my engine use regular bolts. That would mean the only possible adjustment is on the push rod side of the rocker. The repair manual shows an adjuster on the bolt as well as the push rod. Seems off to me.
