Alan, in a stocker engine with a floppy rocker arm, is the extra stiff pushrod that important?
To quote the cliche, "You are only as strong as your weakest link." If you determine the effective stiffness of the rocker arm and then the stiffness of the pushrod, the pushrod is around 20 times more stiff (or stiffer) than the rocker arm. And since these are essentially two springs in series, the lower stiffness drives the total stiffness of the system.
