- Chevrolet Performance LSX-DR Cylinder Head
Capable of over 900 naturally aspirated horsepower!
This is the cylinder head that Chevrolet Performance engineers designed for the 770hp LSX454R engine. These LSX-DR (Drag Racing) 11-degree, six-bolt aluminum heads feature raised-runner designs for improved airflow that supports sustained high-rpm performance. Intake port configuration is similar to the competition-derived C5R head, but the ports are raised an amazing 10mm and the intake manifold bolt pattern is spread to accommodate additional port configurations.
