Dart Marine PRO1 cylinder Head

Features an exclusive chromate surface finish to inhibit corrosion and extend the life of the head.

Fitted with Inconel exhaust valves to withstand the extended running time and temperatures typical of marine usage.

For street performance and mild bracket racing. Under 7,000 RPM, under 500 cubic inches. Excellent mid-range torque and power, good for heavier vehicles.

Inspired by Dart’s championship winning Pro Stock designs, the PRO1’s race proven features include rolled valve angles, improved spark plug location, extra long intake valves, raised exhaust ports, and fast burn chambers – yet the PRO1 310cc can be used with off the shelf pistons, valve train components, and intake manifolds.

Heads are sold individually.

Long wearing Bronze valve guides, screw-in studs, multi-angle intake seats with hardened, radiused exhaust seats are standard. Best of all, our precision cast ports produce outstanding airflow without time consuming porting.

Assemblies include Stainless Steel valves, premium springs, locks, retainers, guide plates and seals.

Heads are sold individually.
