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.
