Dart Pro1 Aluminum Big Block Chevy Cylinder Heads are engineered for street performance and mild bracket racing, providing excellent midrange torque and power for engines under 7,000 RPM and 500 cubic inches. These heads are ideal for applications requiring reliable performance in heavier vehicles, offering a perfect balance of power and efficiency.
Inspired by Darts championship-winning Pro Stock designs, the PRO1 heads incorporate race-proven features such as rolled valve angles, improved spark plug locations, extra-long intake valves, raised exhaust ports, and fast burn chambers. The 310cc version maximizes airflow while maintaining compatibility with off-the-shelf pistons, valve train components, and intake manifolds for ease of installation and cost-effectiveness.
Durability is built in with long-wearing bronze valve guides, screw-in studs, multi-angle intake seats, and hardened, radiused exhaust seats. The precision cast ports ensure outstanding airflow without the need for extensive porting. Assembled with stainless steel valves, premium springs, locks, retainers, guide plates, and seals, Dart Pro1 Aluminum Big Block Chevy Cylinder Heads deliver race-quality performance for street and mild bracket racing applications. Heads are sold individually.
