Maximum competition, comp/modified drag racing, circle track. Over 7,000 RPM, high compression low dome. Dart Race Series 12.5 Deg 296cc CNC heads offer outstanding performance in a raised runner style casting. By reducing the valve angle, reshaping the raised intake ports and optimizing the combustion chambers, we produced a significant increase in both airflow and combustion efficiency. It is recommended that you contact a Dart technical representative before placing an order for this item.
