Harland sharp roller rockers - measure pushrod length

Then how would a person center the rocker on the stem? If I understood some other threads about geometry of the Rockers. Wasn't it you that said mill the stands off for the roller shafts and use your stands. Just trying to figure out how to correct the placement of the roller to the valve stem, and keep geometry correct.
You don't have to mill off the stands with my correction kits, although you can mill off the stands and make new ones. It just costs more, and you have to know how to determine the proper position, not just center the roller and be done with it.

It wasn't me, but you probably heard Yellow Rose talk about milling off stands before I started making my kits.
