SBC Iron Eagle Platinum Heads

The result of three decades of cylinder head developement, Iron Eagle Platinum Series heads incorporate features that were previously available only in expensive aluminum cylinder heads. Using proprietary Speed Flow Technology(tm), Dart has developed more efficient port designs with improved velocity and flow capabilities. The combustion chambers and ports have been redesigned for greater breathing characteristics and more controllable combustion. Casting walls are cleaner and more consistent, resulting in greater control over flow, heat, and combustion.

Iron Eagle S/S Heads

Dart Iron Eagle S/S heads produce great throttle response and low to mid-range torque for street performance engines. Our precision cast ports and chambers produce outstanding airflow without time consuming porting. These heads are a vast improvement over factory originals. Why spend good money reconditioning questionable junkyard parts when you can have a brand new Dart head for a few dollars more.

SBC 12.5, 15, 16, & 18 Degree Heads

Dart 12.5°, 15°, 16° and 18° aluminum small-block cylinder heads offer a dramatic performance improvement over conventional 23° designs. By reducing the valve angle, reshaping the intake ports and optimizing the combustion chambers, we produced a significant increase in both airflow and combustion efficiency.
