that a great idea. but my rocker arm holes are smaller than the pushrod diameter



Great point, also it's not going to work with conventional ball/cup pushrods, the cup will get stuck in the adjuster holes regardless of pushrod size.

Works like a charm with 5/16" one piece ball/ball pushrods and Comp 1321 rockers though, and that's my current setup, so that's why I was thinking about it.
