Chevy LS1 PRO1 CNC Heads |
|
| Dart CNC-ported aluminum cylinder heads for GM LS-series small-block V8 engines take performance to the next level. Dart's CNC LS1 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 CNC LS1 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. |
