Designed for 1997 & later LS based Chevy engines including 4.8L, 5.3L, 5.7L & 6.0L. All E-CNC heads feature fully CNC'd LS3 intake ports, combustion chambers and exhaust ports for improved air-flow.

Match with any one of Edelbrock's LS series intake manifolds and camshafts for a dyno-proven performance combination. Rocker bolt kit p/n 350-8597 includes 8 rocker bolts that are shorter than stock to prevent the bolts from protruding into the intake ports.
