Fleece Performance 03-07 Ford Super Duty 6.0L Powerstroke 20mm Dowel Freedom Series HD Cylinder Head

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 Notes All 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 model Follow 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.

• Re-manufactured OE casting

Upgrade 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. Unlike standard OE castings, this head offers enhanced structural integrity and longevity, ensuring reliable performance under extreme conditions. The re-manufactured OE-style casting undergoes rigorous testing and development to meet high-performance demands, making it suitable for both street and heavy-duty applications.

Equipped with race-proven, extreme-duty tungsten alloy valve seats, this cylinder head delivers superior wear resistance and stability. 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.

Designed specifically for 2-bolt rocker box configurations with 20mm dowels, this cylinder head is compatible with a variety of Ford models from 2003. To optimize installation and performance, Fleece Performance recommends using 6.4L pushrods (Ford Part No. 8C3Z-6565-B), which are slightly shorter than stock 6.0L pushrods, accommodating potential tolerance variations. Please note that head gaskets are not included; Fleece recommends using Ford Part No. KZ3Z-6051-B for proper sealing. Verify your engine serial number and follow the provided flow chart to select the correct model, ensuring optimal fitment and performance. This product is compliant with EPA standards and is ideal for those seeking a reliable upgrade for heavy-duty diesel applications.
