I just broke in my fresh 440. It has Harland Sharpe roller rockers. It's really noisy with clatter. The builder said he likes to set them up "loose" and I may want to tighten them down once I get the engine broken in. I've heard other mopar guys complain about this builder doing the same to them on their RB engine.

Can one of you engine builders give me the 411 on how to properly set the tension on them so that I don't go deaf under the hood?

I’m listening.
