Dart Pro1 Aluminum Big Block Chevy Cylinder Heads are built for serious street performance, mild bracket racing, and marine applications. Designed for engines over 7,000 RPM and 525+ cubic inches, these heads are perfect for high-performance builds that require exceptional airflow at high valve lifts. They are also versatile enough to be used on smaller engines with a tight converter.
The PRO1 24-degree 325cc heads are engineered to increase airflow, making them ideal for high RPM, big cubic inch engines, while still being compatible with off-the-shelf pistons, valve train components, and intake manifolds. With race-proven features like long-wearing bronze valve guides, screw-in studs, multi-angle intake seats, and hardened, radiused exhaust seats, these heads offer unmatched durability and performance.
Darts precision cast ports ensure optimal airflow without the need for time-consuming porting. Assembled with high-quality stainless steel valves, premium springs, locks, retainers, guide plates, and seals, Dart Pro1 Aluminum Big Block Chevy Cylinder Heads provide reliable, top-tier performance for demanding applications. Heads are sold individually.
