Description

Maximum competition, comp/modified drag racing, circle track. Over 7,000 RPM, high compression – low dome.

Dart Race Series 12.5° 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. Detailed information about your planned engine build will help to ensure that you choose the right configuration for your motor and that any special parts and considerations are taken into account.

Heads are sold individually.
