Calculator Compression Calculator

Using Speed Flow technology, computerized modeling, and physical testing, Dart has developed more efficient port designs with improved velocity and flow capabilities, and the results are these Iron Eagle Platinum cylinder heads. The combustion chamber of these heads has been redesigned, and the casting walls made cleaner, for greater breathing characteristics and more controllable combustion. Also featured are hardened exhaust seats for better durability with unleaded fuel, and a 5-angle competition valve job on the intake, with a full radius on the exhaust valve. These heads also accept most stock bolt-on components.
