Improved casting. This isn’t your run of the mill, rinse and repeat OE casting.  Engineered from the ground up with years of testing and development - our higher tensile strength alloy castings incorporate increased wall thickness and additional material where it counts, providing for a more durable and longer lasting cylinder head.Extreme duty valve seats.  Race proven and stronger than OEM – our American made valve seats provide for longevity and stability in the cylinder head. Produced from a tungsten alloy for increased hardness, these seats deliver a substantially higher wear resistance vs. a stock replacement seat.Single piece O-ring. Our 6.0L cylinder head is the only cylinder head available with a single piece hoop style O-ring.  Our single piece O-ring ensures complete sealing of combustion vs. traditional stainless wire that has a seam.Application NotesAll 20mm dowel heads are configured for 2-bolt rocker box configurations.Fleece Performance recommends the use of 6.4L pushrods (Ford Part No. 8C3Z-6565-B) when installing these cylinder heads. 6.4L pushrods are 0.050” shorter in length vs. a 6.0L pushrod and will accommodate the tolerance stack ups that can be encountered with a replacement cylinder head. Head gasket not included. We recommend the use of Ford Part No.KZ3Z-6051-B.Cylinder Head Identification - Selecting the proper modelFollow the flow chart below to determine the appropriate cylinder head and components for your application (this information may also be found in our installation instructions). The engine serial number can be found on the rear, driver’s side of the engine block. An alternate location for the engine serial number can be found on the identification sticker located on top of the fuel injector control module (FICM). This only applies for vehicles with their original FICM. If you are unsure if the FICM is original to the vehicle, read the serial number on the back of the engine block.
