Fleece Performance 03-07 Ford Super Duty 6.0L Powerstroke 18mm 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

The Fleece Performance 6.0L Powerstroke HD Cylinder Head is designed to enhance durability and performance for your Ford Super Duty trucks from 2003 to 2007. Engineered with a focus on strength and longevity, this cylinder head features improved casting technology that surpasses stock OEM units. Constructed from a higher tensile strength alloy, it incorporates increased wall thickness and additional material in critical areas, resulting in a more durable component capable of withstanding extreme conditions and extended use. This advanced casting process ensures a reliable foundation for high-performance applications and heavy-duty use. The cylinder head is equipped with race-proven, tungsten alloy valve seats that provide superior wear resistance and stability, optimizing engine longevity. These seats are produced domestically in the United States and are designed to withstand the rigors of demanding driving environments, offering enhanced performance and reduced maintenance intervals. One of the standout features is the single-piece hoop style O-ring, exclusive to this model, which guarantees a complete and reliable seal for combustion chambers. Unlike traditional stainless wire seals that can develop seams, this design prevents leaks and maintains optimal compression levels for improved engine efficiency. Compatibility is specific to 2-bolt rocker box configurations with 20mm dowel heads, and Fleece Performance recommends using 6.4L pushrods (Ford Part No. 8C3Z-6565-B) during installation to accommodate tolerance variations and ensure proper fitment. Please note that head gaskets are not included; Ford Part No. KZ3Z-6051-B is recommended for sealing. To determine the appropriate cylinder head for your vehicle, follow the provided flow chart and locate your engine serial number on the engine block or FICM. This cylinder head is essential for owners seeking to upgrade their engine's durability and performance in demanding applications, backed by rigorous testing and American manufacturing standards.
