PRO1 series aluminum cylinder heads feature high flowing as-cast ports with profiled valve guide bosses and are bowl blended on 5-axis CNC machining centers. The ports and chambers have been designed using Dart's sophisticated Wet Flow Technology for superior fuel atomization and airflow characteristics. Standard valve angle and spacing is retained for bolt-on compatability. Exhaust runners are raised . 135" for improved flow. Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels.
