Roller rocker choice for HYD rollercam/for High Miles-Full life

A lot of time when they break the stands, people forget that you sometimes need to oval the holes in the shaft to allow it to "go" where the shims want it too. They tight it down, put everything in a bind and "SNAP". That's why Mike @B3RE is so good. He TELLS you about all that ahead of time so you have the tools and knowledge to do it right. The guy just flat knows his stuff and is an asset to this community.
Most of the shafts have a larger hole than the 5/16 bolt that goes through, it moves fine with the shims...aside from stacking them that is.
Tightening them unevenly is what I've seen do some harm.
