Dart SB-Chevy Iron Eagle Platinum Series Cylinder Heads Product images may differ from actual product appearance. 10% More Air Flow 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. Other features include: Hardened exhaust seats for better durability with unleaded fuel Phosphorus exhaust guides, manganese intake guides 5-angle competition valve job on intake, full radius on exhaust valve Accepts most stock bolt-on components Click on the flow chart to see the gains!
