If you’re tearing down your 2006–2007 Ford 6.0L Powerstroke, don’t reuse tired, worn-out heads—replace them with the Powerstroke Products Loaded Stock O-Ringed Cylinder Head, built for performance and reliability. Designed for 20mm dowel engines, this head features a precision-machined O-ring groove to help keep combustion sealed in the cylinder and out of the cooling system—critical for tuned and high-boost trucks.
Starting with a brand-new casting (no core required), each head is inspected to meet Powerstroke Products’ strict quality standards and is then fully assembled with new valves, springs, and seals. It arrives ready to install, making it a smart and efficient upgrade for your build.
