Edelbrock Cylinder Head E-Cnc 212 GM Gen IIi Ls Complete

If you're looking to get more performance out of your Gen III or Gen IV LS engine, a set of Edelbrock E-CNC cylinder heads can make a big difference. These heads are designed for LS1, LS2, and similar displacement engines like the 4.8L, 5.3L, 5.7L, and 6.0L found in a wide range of vehicles, from the Chevrolet Camaro and Corvette to the Pontiac GTO and Cadillac CTS. They are a popular choice for high-performance street applications and light-duty racing, aiming to unlock more horsepower and torque from your engine.

What sets these heads apart is the fully CNC-machined intake ports, exhaust ports, and combustion chambers. This precision machining ensures consistent airflow across all cylinders, which is crucial for maximizing engine efficiency and power output. Edelbrock's testing shows these heads are capable of supporting builds that reach 457 horsepower and 438 ft-lbs of torque. They come equipped with high-quality conical beehive springs, steel retainers, and valve locks that are rated for valve lifts up to .600 inches, making them ready for many popular camshaft upgrades. For a complete, dyno-proven performance package, Edelbrock recommends matching these heads with their LS series intake manifolds and camshafts.

When installing these heads, remember that the rocker bolt kit #8597 is recommended. It includes shorter rocker bolts designed to prevent them from protruding into the intake ports, which is a common concern with some LS engine builds. While this specific part number is for the E-CNC 212 head, note that the E-CNC 215 head variant is 50-state street legal, so always check local regulations for your specific application.
