The ultimate wedge head for 572″ engine. Big engines require superior air flow when 900 to 1,000 horsepower is the goal. The 572-13 head is designed for a 4.500″ bore with the valves moved on center. This allows the exhaust valve to be moved and a larger diameter intake valve to be utilized. This combination delivers excellent torque, horsepower and reliability needed to make a bracket racer consistant, round after round.
The 572-13 heads respond best when used with the 400-3X big volume 4500 intake manifold. If you are searching for more power select the 440-15 Indy tunnel ram intake manifold. These combinations produce a 572 engine that is a lightweight Maxx power combination just waiting to win.
