Dart's GEN III heads feature high flowing as-cast ports with standard valve angle and spacing allowing readily available components to easily be bolted in. Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels. Valve bowls are blended on 5-axis machining centers for maximum flow potential out of the box.
