DART Pro 1 Aluminum Cylinder Heads for SBF
Dart's Ford Pro 1 Cylinder Heads are cast from the same virgin 355-T6 aircraft alloy that is used in Dart Pro-Stock heads. These Windsor style heads are available with high flowing as-cast ports. Standard valve angle and spacing is retained for bolt-on compatability. Exhaust runners are raised 0.135" for improved flow. The exhaust flange uses the standard pattern on as-cast heads. As cast heads are bowl blended on 5-axis machining centers. Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels. Whether you're building a mild street engine or a big inch fire breather, Dart heads will give you a performance advantage!
