Dart's PRO1 15* LS CNC ported Aluminum cathedral port cylinder heads take performance to the next level!

This LS CNC cathedral port 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, these heads are recommended for engines with a 4.000" bore and larger.  Precise CNC machining, multi-angle intake seats, and radiused exhaust seats enhance airflow.  Extra material above the ports accommodate valve train upgrades.
