For your application, it's a waste of money IMO. All that money spent to upgrade your lift from 484 to 516. Run a set of hd stamped rockers and be done with it. You can spend money on a new cam with a modern lobe rate like a comp xe-hl or a lunati voodoo and get more than 516 lift with a similar duration, and still not require adjustable rockers. With roller rockers and the issues they have(especially the cheapies), IMO it makes no sense to buy them for your combo. I know some guys are dead set on adjustables, but for your combo I think they're a terrible bang for your buck at this point.
