VALVE SPRINGS 1.55in OD 228 at 2.05/636 at 1.3

Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift.Comp Cam's dual valve springs, Outer spring 1.55 inch outside diameter and 1.125 inside diameter, Inner spring .719 inch inside diameter, 549 lbs./in. rate, 1.192 inch coil bind height, Set of 16.
