These "X-Head" heads use GT-40 performance intake manifolds, and feature high temperature exhaust valve seats with bronze guides. For 289 and 302 block applications, you must use head bolt kit M-6065-D289 or the bolt and gasket kit M-6051-D50 to ensure proper installation.

    "Z-Head" cylinder heads are designed for the 302 or 351 Windsor-style engines. Cast with high-flow ports and 20 degree inline valves, these heads feature steel alloy intake and exhaust valve seats with bronze valve guides (on assembled models). These "Z-Head" cylinder heads require M-6564-F351 or M-6564-G351C roller rocker arms with .150" offset intake pushrod cup.

  • Fitment With 302 or 351 Windsor Engine Blocks

  • Intake ports feature a unique "Velocity Vane" in port floor to direct airflow around the valve stem – that leads to more HP and torque throughout the full power range
