ROCKER ARMS This item is for sixteen (16) rocker arm kits with grooved fulcrums for 1987-2002 Chevrolet 265ci, 305ci, and 350ci small block V-8 engines. P/N (16) RK-2736. Buyer will receive (16) rocker arms, (16) rocker nuts, and (16) grooved rocker fulcrums. We recommend the use of grooved fulcrums for any performance or high lift application. The grooved fulcrums provide better lubrication in the rocker arm pocket. FALCON TECH NOTE : Never install new rockers dry. They must be lubricated during initial start-up with the proper lubricant to avoid permanent damage. A generous amount of lubricant on each rocker arm, pivot ball, bushing pushrod tip, and valve tip can prevent damage to new parts.
