ACDelco GM Genuine Parts Cylinder Heads
Great cylinder-head airflow has been a key enabler of the LS-Series exceptional performance. ACDelco GM Genuine Parts cylinder heads deliver those power building attributes to you with a range of production-style aluminum heads. GM Genuine Parts are designed, engineered and tested to rigorous standards, and are backed by General Motors. From the LS6 heads for smaller-displacement engines to LS7 style heads for 427-inch-and-larger combinations, these aluminum cylinder heads benefit from Chevrolet Performance's extensive research and development program, providing maximum airflow. Many assembled heads use premium machining and materials, including CNC finishing and porting, along with lightweight, hollow-stem valves, sodium-filled exhaust valves, and on some heads lightweight titanium intake valves.
