Chevrolet Performance LS3 CNC Ported Aluminum Cylinder Head
The Chevrolet Performance LS3 CNC Ported Aluminum Cylinder Head design benefits from General Motors' extensive research and development program, ensuring maximum airflow without compromises. In fact, many professional builders use this head as straight bolt-ons, with no further machining. These assembled heads use premium machining and materials, including CNC finishing and porting, along with lightweight, hollow-stem intake valves and sodium-filled exhaust valves to provide your engine with the power increase you have been searching for!
