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.\n\nExtreme 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.\n\nSingle 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.\n\nApplication Notes\nAll 20mm dowel heads are configured for 2-bolt rocker box configurations.\nFleece 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. \nHead gasket not included. We recommend the use of Ford Part No.KZ3Z-6051-B.\n\nCylinder Head Identification - Selecting the proper model\n\nFollow 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.\nRecommended Cross Sell Skus - FPE-6.0STREET-0304 FPE-6.0STREET-0407 FPE-HAR-FMC-CAM-0310\n\u003cul\u003e\n  \u003cli\u003eRe-manufactured OE casting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade your 2003-2007 Ford Super Duty with the Fleece Performance FPE-61-10012-HD cylinder head, engineered for durability and performance. Crafted from an advanced high-tensile strength alloy, this cylinder head features an improved casting design that incorporates increased wall thickness and additional material where it matters most.

These seats are stronger than stock and engineered to withstand high temperatures and pressures, extending service life and maintaining optimal engine performance. The unique single-piece hoop style O-ring ensures a complete seal of combustion chamber gases, eliminating leaks common with traditional seam-based stainless wire seals. This design enhances engine efficiency and helps sustain power output over time.\u003c\/p\u003e\u003cp\u003eDesigned specifically for 2-bolt rocker box configurations with 20mm dowels, this cylinder head is compatible with a variety of Ford models from 2003.
