The LS Family Production and C5R Aluminum Heads
Great cylinder-head airflow has been a key enabler of the LS Series exceptional performance. GM Performance Parts delivers those power-building 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 General Motors extensive research and development program, ensuring maximum airflow without compromises. In fact, many professional builders use our heads as straight bolt-ons, with no further machining. 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.
