Dart Pro1 Aluminum Big Block Chevy Cylinder Heads are designed for street performance, mild bracket racing, and marine applications. They are suitable for engines under 6,800 RPM and under 500 cubic inches, offering excellent mid-range torque and power, which is beneficial for heavier vehicles. Key features include a new high-velocity oval port design, rolled valve angles, improved spark plug location, extra-long intake valves, raised exhaust ports, and fast-burn chambers. The heads come standard with long-wearing Bronze valve guides, screw-in studs, and multi-angle intake seats with hardened, radiused exhaust seats. Precision cast ports produce outstanding airflow without the need for time-consuming porting. Assemblies include Stainless Steel valves, premium springs, locks, retainers, guide plates, and seals. 110cc chamber heads are available upon request, and heads are sold individually.
