Dart’s highly popular PRO 1 cylinder heads now benefit from the proprietary Speed Flow™ technology which revolutionized the Iron Eagle line a year ago with the platinum series. Wet flow testing and advanced manufacturing techniques have produced redesigned ports and chambers, resulting in greater breathing characteristics and more controllable combustion.
