I had read that the new rollers gave a little more lift for the valves with the way they are made. Off of Cranes website.

The rocker arms are manufactured from heat-treated billet aluminum extrusions, and CNC machined to exacting tolerances. These gold anodized rockers have long had the reputation of being the most accurate on the market and feature Crane's exclusive Quick-Lift™technology. They employ heavy-duty precision-ground steel needle bearings, a heat-treated steel roller tip, and come complete with adjustable locking nuts.
