The deflection I've measured is about .015" from checking spring to race springs on my 396 stocker motor. This is a combination of the pushrod flex, rocker stud flex and the rocker arm itself, not sure how you'd isolate the amount in the rocker alone but it is significant. NHRA checks lift at the retainer, using a solid lifter of the same height, so you can adjust the lobe lift to compensate for the loss from what I understand....
