ACDelco® - GM Genuine Parts™ Engine Cylinder Head Assembly

GM Genuine Parts™ Engine Cylinder Head Assembly by ACDelco®. Cylinder Head with Valves. Great cylinder-head airflow has been a key enabler of the LS-Series - exceptional performance. Chevrolet Performance delivers those powerbuilding attributes to you with a range of production-style aluminum heads. From the LS6 heads for smaller-displacement engines to LS7 style heads for 427-inch-and-larger combinations, our aluminum heads benefit from Chevrolet Performance's extensive research and development program, providing maximum airflow. Many of our 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. NOTE: Chevrolet Performance heads will not fit 4.8L and 5.3L engines, due to their similar bore sizes.
