SB Ford Dart Pro 1 Aluminum Cylinder Heads

Inspired by Dart's championship winning Pro Stock designs, Dart Pro 1 aluminum cylinder heads cover a wide range of applications from street cars and trucks to all-out racing. Heads designed for street performance and mild bracket racing offer excellent mid-range torque and power, and are excellent for heavier vehicles. Competition heads are ideal for maximum effort naturally aspirated, big boost forced induction, or nitrous applications. Dart Marine Pro 1 cylinder heads feature an exclusive chromate surface finish to inhibit corrosion and extend the life of the head. They are also fitted with Inconel exhaust valves to withstand the extended running time and temperatures typical of marine usage.

Serious street performance, mild bracket racing and oval track. Maximum torque and throttle response from 3,500 to 7,800 RPM. Best for 363-427 cubic inch engines. Works with most standard components.

Every intake port, exhaust runner, valve bowl, and every combustion chamber is 100% CNC machined on special dedicated PRO1 castings. These Head are ideal for high compression, big cubic inch small blocks and are great for supercharged applications.

Exhaust runners are raised .135” for improved flow. Manganese Bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels. Features 3.000″ exhaust bolt pattern.

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