Chevy LS1 PRO1 Heads |
Dart's new aluminum cylinder head for GM LS-series small-block V8 engines offers higher performance and more versatility than factory designs. The Dart LS1-style high performance
cylinder head has better airflow, more efficient combustion, and more user-friendly features than production LS1 castings - and costs less than comparable OEM heads. The Dart LS1-style cylinder head retains stock valve angles, stock valve locations and stock accessory mounting holes to make installation easy. Virtually everything else has been improved. |

Chevy LS1 PRO1 CNC Heads |
Dart's CNC LS1 head is machined on a dedicated casting with extra-thick sections to maintain the proper wall thickness after porting. Precise computer-controlled CNC machining, multi-angle intake seats, and radiused exhaust seats enhance airflow, while manganese bronze valve guides and interlocking valve seats ensure long-term reliability. Extra material above the ports accommodates valvetrain upgrades.
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. |
