WE HAVE MADE 730HP ON THESE ROCKER ARMS WITH .744 LIFT CAMSHAFT ON JOHNSON SHORT TRAVEL LIFTERS. THESE LIFTERS FIT THE HEADS CORRECTLY AND ARE LIGHTENED OVER THE NOSE AND MADE OF STRONG STEEL WITH FULL ROLLER OVER THE VALVE TIP AND TRUNNION. DO NOT BUY HEAVY CLUCKY ALUMINUM AFTER MARKET ROCKERS FOR YOUR LS--TRUST ON OF THIS. THESE ARE ALMOST AS LIGHT AS GM CAGED TRUNNIONS BUT HAVE SEVERE DUTY ROLLER ON VALVE TIP. THIS OR THE CAGED GM ROCKERS ARE THE ONLY SET-UP WE TRUST ON OUR LS ENGINES, AND HAVING ROLLER TIP ON VALVE IS A NICE THING TO HAVE TO REDUCE VALVE STEM TIP WEAR AND GUIDE WEAR AND REDUCE CHANCES OF DROPPED VALVES OR BROKEN VALVES WITH HIGH LIFT CAMSHAFTS.
