Dart Pro1 Aluminum Big Block Chevy Cylinder Heads are designed for serious street performance, mild bracket racing, and marine applications. Ideal for engines exceeding 7,000 RPM and 525+ cubic inches, these heads excel in high-performance environments but are versatile enough to be used on smaller engines with a tight converter.
The PRO1 24-degree 325cc heads provide significant airflow improvements at high valve lift, making them perfect for high RPM, big cubic inch engines. Despite their focus on maximizing airflow, these heads remain compatible with off-the-shelf pistons, valve train components, and intake manifolds, making installation and integration hassle-free.
These heads feature long-wearing bronze valve guides, screw-in studs, multi-angle intake seats, and hardened, radiused exhaust seats for durability and high performance. Darts precision cast ports ensure optimal airflow without the need for extensive porting, making these heads ready to perform right out of the box. Assemblies include stainless steel valves, premium springs, locks, retainers, guide plates, and seals. Dart Pro1 Aluminum Big Block Chevy Cylinder Heads deliver maximum performance for serious street, racing, and marine builds. Heads are sold individually.
