ProMaxx Performance has the answer for the epidemic of cracked GM 6.5L cylinder heads. They have developed and designed this new cylinder head from the OE casting but improved the casting strength and thickness in all the crack prone areas. This is a direct bolt-on cast iron cylinder head that replaces your difficult to access fractured factory cylinder heads. This head is available as a fully machined bare casting or fully assembled and pressure checked!
The "Standard" or "Straight" cylinder head will typically use a 1-piece intake manifold and are normally found in Pickup applications. The "Angled" cylinder head will use a 3-piece intake manifold and are commonly found on Vans and Hummers. Please confirm what is in your vehicle before ordering.
