Chevrolet Performance LT1 CNC Ported Cylinder Head

The Chevrolet Performance LT1 CNC Ported Cylinder Head is a precision-engineered upgrade designed to unlock the true airflow and power potential of your LT-series engine. Built from high-quality aluminum and finished with computer-controlled porting, this head delivers improved intake and exhaust flow compared to stock castings, resulting in better cylinder filling, stronger torque, and higher peak horsepower.

CNC porting ensures consistent, optimized airflow through the intake and exhaust runners and combustion chambers, with precision shaping that traditional hand porting can’t match. By removing casting irregularities and smoothing critical airflow paths, the ported LT1 head supports enhanced combustion efficiency and more complete power strokes—especially beneficial on modified or high-performance builds.
