    Don't let a warped cylinder head sideline your Ford 6.0L Powerstroke (2003-2006 with 18MM Dowels). The Fleece Freedom Series HD 18mm 6.0L Cylinder Head (FPE-61-10011-HD) is not just a replacement; it's a critical upgrade engineered for superior longevity and relentless reliability. Manufactured within Fleece's cutting-edge Freedom Racing Engine shop, this head is a testament to meticulous engineering. It starts with a brand-new casting that dramatically improves upon the original design by using a higher tensile strength alloy, incorporating greater wall thickness, and adding material where it's needed most. This results in a cylinder head built to withstand the stresses of heavy-duty towing and the demands of a daily driver, making downtime a thing of the past. It comes fully assembled and ready to install—no core charge or return required—and features a host of premium, race-proven components, including a one-piece O-ring design for maximum cylinder sealing.

    • Improved Casting: Engineered from the ground up, this brand-new, higher tensile strength alloy casting features greater wall thickness and additional material in high-stress areas for a more durable and longer-lasting product.
    • Extreme-Duty Valve Seats: These American-made, race-proven seats are manufactured from a tungsten alloy for superior hardness and substantially higher wear resistance compared to factory units, offering unmatched longevity and stability. They are also hardened and oversized press-in for maximum durability.
    • Single-Piece O-Ring: Fleece's exclusive single-piece hoop-style O-ring design ensures a complete and continuous seal of combustion, outperforming traditional seamed stainless wire.
    • Ready-to-Install Assembly: Each head includes an all-new valvetrain featuring Stainless Steel and Inconel alloy valves, springs, retainers, and keepers, along with new valve guides and valve seals.
    • Direct-Fit and Simple: This is a direct-fit replacement that meets or exceeds factory specifications, and Fleece eliminates the hassle with No Core Charge or Core To Return.
    • Peace of Mind: Backed by a 1-Year Limited Manufacturer Warranty.

    Choosing the Fleece Freedom Series HD 18mm Cylinder Head is a strategic investment in the future of your 6.0L Powerstroke. By utilizing a brand-new, fundamentally improved casting and incorporating race-proven components like the tungsten alloy valve seats and the exclusive single-piece O-ring, Fleece delivers an assembled unit that is engineered to exceed factory standards for reliability. For applications where your truck’s dependability is non-negotiable—be it your workhorse for heavy towing or your critical daily transportation—this cylinder head provides the ultimate assurance against premature failure. Install this head and drive with confidence, knowing your engine is protected by the best in aftermarket diesel performance.


    Note:
    • Head gasket not included. Fleece recommends the use of Ford Head Gaskets.
    • All 18mm dowel heads are configured for use on 8-bolt rocker box configurations.
    • If your engine serial number is 6,000,000 to 6,723,721 (or 1 to 299,092) you need 18mm cylinder heads.
    • All 18mm heads are configured for use with early style injector clamps with a T40 fastener - Ford 3C3Z-9C995-AA Fuel Injector Hold Down Clamp.
    • Fleece Performance recommends the use of Ford 8C3Z-6565-B Replacement Pushrod when installing this cylinder head. The 6.4L pushrods are 0.050" shorter in length than the 6.0L pushrod and will accommodate the tolerance stack-ups that can be encountered with a replacement cylinder head.
