Dart 10310010PF Iron Eagle Bare Chevy Cylinder Head, 200cc/49cc

Using proprietary Speed Flow technology, 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 better control over flow and heat.
