    Ford Racing Cylinder Heads

    Cast from 356-T6 aluminum, these cylinder heads from Ford Racing are the perfect solution for bolt on horse power! Weighing in at approximately 22lbs (half the weight of cast iron heads!), these cylinder heads are available in three styles, "X-Head", "Z-Head" and "Z2-Head".


    X-Head Cylinder Head
    "X-Head" cylinder heads are designed for the 289, 302 or 351 Windsor-style engines. 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.

  • Fitment With 289, 302, or 351 Windsor Engine Blocks
  • Gasket Seat Style Spark Plugs
  • Bolt-On 65 Horsepower


    Z-Head Cylinder Head
    "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
  • Tapered Or Gasket Seat Style Spark Plugs
  • Stainless Steel Intake And Exhaust Valves (On Assembled Models)


    Z2-Head Cylinder Head
    The "Z2 Head" aluminum small block Ford cylinder head features an advanced "Velocity Vane" intake port design that delivers outstanding street/strip power. Developed with the aid of advanced computer aided Engineering simulation tools, the unique "Velocity Vane" intake port design improves power throughout the RPM range. This high performance aluminum cylinder head is a direct bolt on for Ford 289/302/351W engines and retains OEM exhaust, intake, rocker arm and accessory mounting locations.

  • Fits 289/302/351 Windsor engines
  • Cast from prime 356 T6 aluminum
  • Heads retain Ford OEM intake and exhaust port location and flange
  • 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
  • 20° degree inline valve angle
  • Premium stainless steel 2.05" intake; 1.60" exhaust valves
