I bet you didn’t know we offer upgraded 6.0 Powerstroke cylinder heads from Kill Devil Diesel. 🐾
We offer these KDD heads because they are engineered for the higher heat, pressure, and load seen in performance and heavy-use Powerstroke applications. Each head starts as a heavy-duty casting thicker than OEM, then goes through a full inspection and proprietary machining process. This includes a multi-angle valve seat profile for improved sealing and heat transfer, corrected valve height to eliminate excessive lifter preload, and deeper valve recession for increased piston-to-valve clearance. The gapless O-ring system is pressed directly into the casting and is the same design proven in Diesel Power Challenge testing.
Every head is pressure-tested to 60 psi and assembled with all-new valves, valve springs, retainers, locks, seals, freeze plugs, and sleeves. Springs are individually tested and matched, and ports are vacuum-tested to verify proper sealing. Additional features include tungsten carbide seat inserts, press-in iron-matrix guides, upgraded casting thickness, and optimized valvetrain geometry. These are 100% new cylinder heads with no core charge required.
