You are comparing apples to oranges.

THAT is a SB Chevy that has an adjustable rocker pivot mount. That video does not apply to any engine that has a fixed rocker pivot like our Saitos, or SB Chryslers Fords etc.




While the geometry does change, the net valve lift will not change a significant amount when the change is at the pushrod/rocker interface . As long as there is sufficient adjustment available, there would be little benefit in changing pushrod length.
