10% More Airflow than the Original Iron Eagle Heads

In 1997, Dart revolutionized the small block cast iron cylinder heads market with the release of the Iron Eagle. Now, Dart gives you the next generation Iron Eagle known as the Platimum Series. Using proprietary Speed Flow technology, Dart has developed more efficient port designs with improved velocity and flow capabilities. Computerized modelling and physical testing have been employed to produce the premier cast iron cylinder head on the market today. The combustion chamber has been redesigned for greater breathing characteristics and more controllable combustion.

Dart's casting techniques have been enhanced to reduce potential core shift, and to improve dimensional accuary. This has allowed Dart to design profiled valve guide bosses for higher flow rates. Casting walls are cleaner and more consistent, resulting in greater control over flow, heat and combustion.
