With a big rocker, the pushrod side weight becomes even less important vs. valve side.
Would my understanding of kinematics mean "important" by a simple factor of the rocker arm ratio being used?
From a simple observation, for the same lift rate and height at the valve, the help would come in the form of reduced ramp speed and lift required on the pushrod side. But because often the same cam lobe would be used, now the added rate of valve, retainer, locks, rocker and spring opening speed and total lift will add to the needed spring rate.
