Features

• Brand-new, higher tensile strength casting
• Race-proven formula with hardened, oversized press-in valve seats provides maximum durability and longevity
• Fleece Performance exclusive single-piece O-ring design ensures complete combustion sealing vs. traditional stainless wire that must be seamed.
• New valvetrain including Stainless Steel/Inconel alloy valves, springs, retainers, and keepers
• No core charge or core to return.
• 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.
• 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 inch 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.
• Fits: 2003-2007 Ford F250/2003-2007 Ford F350/2003-2007 Ford F450/2003-2007 Ford F550
