The kit includes 5/16 inch guideplates and push-rods. The Magnum rocker arms have been dyno tested to produce 15-20 horsepower increases. The reduced friction also makes valve stems and guides last longer. Their long slot design allows you to use camshafts with much higher lift than stock cams. Each set of 16 rockers is supplied with a rocker ball and lock nut. For 1.6 ratio use Part # 28782.
