| Dart's Small Block Ford Cast Iron Cylinder Heads are Windsor style performance replacements for the under-performing stock Ford heads at an extremely attractive price. They come standard 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 and the exhaust flange uses the standard pattern on as-cast heads. Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels. Whether you are building a mild street engine or a track champion, Dart heads will give you a big performance advantage! These heads are legal for many oval track sanctioning bodies.
