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.
