This Chevrolet Performance LS9 Cylinder Head is the same one used to produce the impressive ZR-1 Corvette LS9 Engine! This limited production head features the same strength and durability as the production head with the added airflow enhancements of precision CNC porting. To withstand the abuse the engineers at Chevrolet loaded this cylinder head with features including lightweight valves, extra-strength casting with re-enforced webbing and a thicker deck surface for minimal distortion making it ideal for use on supercharged or turbocharged engines!
