FORD 6.0 DSL 2006/07 20mm, NEW BARE


ProMaxx Performance has the answer for the epidemic of cracked Ford 6.0L 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. The ProMaxx casting features hardened seats and true press-in guides instead of the ‘cut into’ like the factory ford head. This head is available as a fully machined bare casting or fully assembled and pressure checked to 60 psi!
