Chevrolet Performance LSX-SC Cylinder Heads

Chevrolet Performance LSX-SC cylinder heads are developed for big-boost levels and high-horsepower engines. Undergoing a Hot Isostatic Pressing (HIP), this process is a way of casting that removes the air pockets while improving the mechanical properties of the components. LSX-SC cylinder heads are the same ones you'll see on Chevrolet's COPO 350 engine. They're available in three different configurations: as-cast; bare with CNC-machined features; or fully assembled CNC-machined cylinder heads complete with valves and springs.

Features and benefits include:

* Signature LSX 6-bolt head-clamping pattern
* Increased deck thickness from 0.650 in. to 0.750 in.
* Exhaust face thickness increased from 0.177 in. to 0.300 in.
* Dense T356 aluminum material
