Dart Pro1 250 LS1 CNC Assembled Aluminum Cylinder Head

Dart CNC Ported aluminum cylinder heads for GM LS series small block V8 engines take performance to the next level.

Dart's LS1 CNC head is machined on a dedicated casting with extra thick sections to maintain the proper wall thickness after porting. Due to the large diameter intake valves, the dart LS1 CNC head is recommended for use on engines with 4.00 inch and larger cylinder bores. Precise computer controlled CNC machining, multi angle intake seats, and radiused exhaust seats enhance airflow. Extra material above the ports accommodates valve train upgrades.

The consistencey and accuracy of CNC machining makes every CNC ported Dart head virtually identical. Our automated five axis machining centers port heads with incredible accuracy, and you get the perfomance benefits at a very affordable price!
