Edelbrock E-CNC 215 LS1/LS2
Designed for 1997 & later GEN 3 & 4 LS1/LS2 Chevy engines including 4.8L, 5.3L, 5.7L & 6.0L. All E-CNC heads feature fully CNC'd intake ports, combustion chambers and exhaust ports for improved air-flow.
Dyno tests proved these heads are capable of 457 hp & 438 ft-lbs. of torque. High-quality conical beehive springs are secured with steel retainers and valve locks for performance up to .600° valve lift. Match with any one of Edelbrock's LS series intake manifolds and camshafts for a dyno-proven performance combination. Rocker bolt kit #8597 includes 8 rocker bolts that are shorter than stock to prevent the bolts from protruding into the intake ports. E-CNC 215 head is 50-state street legal.
