A 1.5:1 rocker will move a valve 1.5 times the lift of the cam. A 1.6:1 rocker / 1.6 times which equates to roughly a 5 to 6% increase in valve lift thus gaining a few extra hp. Dont think it affects duration but do put less load on the valve and add to longevity / friction.. Worth it ?? Just depends on engine setup and how you value your motor. A-series have a pretty tough rocker from factory. I am using them which needed a higher tower. My motor is not fully assembled yet so no testing too.
