Gold Race Extruded Aluminum Roller Rocker Arms for LS1/LS6
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. Stock 1.7:1 and optional 1.8:1 ratios available.
Select Category
The 454/502 Mag cam is a single 224°/224° pattern cam.
How about using a 1.7 ratio on the intake valves and the 1.8 ratio on the exhaust?

Also did you know the o-ring gasket was more expensive than the head gasket?
