This is where I'm understanding it now. I am better off being off center and pushing straight on the axis of the valve stem, or close to it, then to have +.100 scrub on the center.
I'll have to order longer push rods than I expected.
Within reason. If your rocker is going off the valve tip though then you have something besides pushrod length wrong. Unless you can adjust the pivot of the rocker laterally (closer or further from the valve stem) then you're very likely to have your wipe pattern off center which is not best but okay as long as you have minimal scrub. To have the perfect layout you'll need to move the pivot point and adjust the pushrod length, but that's going a bit far for most people,
