Crane Cams Gold-Race, full-roller aluminum rockers for the LS1/LS6 engine family add up to 20 horsepower over stock! These rockers were designed for quiet operation and do not trigger the stock GM "Knock Sensor", which retards spark advance and reduces power output! They feature the exclusive Crane "Quick-Lift" design, which moves the valve off its seat quicker, initiating flow into the combustion chamber earlier, thereby increasing port efficiency and horsepower output! They are available in a complete kit (rockers, rocker studs, pushrod guideplates and pushrods) or separately, and are an easy bolt-on. They also clear stock Chevy LS1/LS6 rocker covers. 1.8:1 ratios.

it does make your cam bigger in duration and lift it will make your cam 550 lift
