COMP Cams 4779-8 Big Block Chevrolet Exhaust Rotator Eliminator
COMP Cams 4779-8 Big Block Chevrolet Exhaust Rotator Eliminator Thickness:.300" - Valve Spring Seat Spacers, Steel, Black Oxide, .300 in. Thickness, Chevy, Big Block, Kit
Late model Big Block Chevy engines are originally equipped with exhaust valve rotators. Until now, the only way to make up for the rotator was to stack .300" of shims under the spring; this sloppy at best. Comp Cams Rotator Eliminators will locate the spring with an outside step so the spring cannot "walk" around on the head.
