Adjustable rocker ratio

Even with a perfect 1.5 ration rocker..the mopar la engine is going to lose lift at the valve due to the angle of the pushrods...

How much? I wonder that have anything to do with the ball/cup or ball/ball design.
Did the clay/puddy test to make sure I wouldn't hit the piston and I got max lift. Mind you he did use hyd roller that were soaked in oil prior.
