6.4 Powerstroke Loaded O-Ring Cylinder Head – DK Engine (DK-FD6.4-CHLO) Single Cylinder Head | 2008–2010 Ford 6.4L Powerstroke
Restore reliability and eliminate the most common failure points on your 2008–2010 Ford 6.4L Powerstroke with this brand new Loaded O-Ring Cylinder Head from DK Engine (Part # DK-FD6.4-CHLO).
This is a single cylinder head (one head per listing). Two heads are required for a complete engine.
Factory 6.4L heads are notorious for head gasket failures and cracking around the glow plugs and valve seats. This upgraded head solves those problems with a reinforced new casting and a precision-machined O-ring sealing design that delivers a much tighter, more reliable combustion seal than stock.
Key Features & Benefits
- O-Ringed Deck — Precision-machined O-ring groove with stainless wire provides superior head gasket sealing. Dramatically reduces the risk of head gasket blowouts, especially on tuned, boosted, or heavily worked trucks.
- Reinforced New Casting — Stronger than OEM in critical areas to help prevent cracking around glow plugs and valve seats — a very common factory failure.
- Fully Loaded & Ready to Install — Comes complete with new Nitride valves, valve springs, seals, retainers, keepers, hardened valve seats, and injector cups. Saves significant machine shop time and labor.
- No Core Charge — Brand new casting. No need to return your old head.
- Direct Fit Replacement — Engineered as a bolt-on solution for all 2008–2010 6.4L Powerstroke engines.
Fitment
- 2008–2010 Ford F-250, F-350, F-450, F-550 Super Duty with 6.4L Powerstroke Diesel
- Direct replacement for OEM cylinder heads
Recommended Supporting Parts
- Quality MLS head gaskets (O-ring compatible)
- Head studs (strongly recommended, especially for tuned or high-horsepower builds)
- Proper torque procedure
Warranty
1-Year Limited Warranty
This is one of the best reliability upgrades you can make to a 6.4L Powerstroke. Whether you're repairing a failed head gasket, doing a preventive overhaul, or building a stronger street/towing truck, this loaded O-ring head gives you peace of mind and long-term durability.
Note: This listing is for one (1) cylinder head.
