Dart Cylinder Heads

Dart's Cylinder Heads are cast from the same virgin 355-T6 aircraft alloy that is used in Dart Pro-Stock heads. These LS-style heads are available with high flowing as-cast ports. Standard valve angle and spacing is retained for bolt-on compatability. 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.production, however. We are constantly redefining our products to bring our customers the best performing components at incredible value. Da

rt's new custom designed and built wet flow bench is an example of our commitment to excellence. Capable of replicating the flow characteristics of a 600ci Pro-Stock engine at 10,000rpm, this one of a kind device enables us to analyze cylinder head flow properties in a whole new light. The result is redesigned ports and combustion chambers which produce significant increases in real world power.
