Each cylinder head is manufactured in our state-of-the-art Freedom Racing Engine shop and is guaranteed to meet or exceed factory specifications. Our HD cylinder heads are built on a brand-new casting that has been engineered from the ground up for increased durability and longevity. Fully assembled and ready to install - all heads are equipped with hardened, oversized press-in valve seats, new valve guides, springs, valves, and valve seals. Standard with our one-piece O-rings in the head to ensure maximum cylinder sealing. Perfect for a daily driver or heavy-duty towing application where reliability and uptime are a must.
Highlights:
- 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.
Note:
- 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.
