KDD ICON Series Street Port Cylinder Heads offer superior performance to anything else on the market - using state of the art casting technologies we molded the ports to improve airflow and cylinder swirl beyond what is possible within the limitations of factory style castings. The ICON series was a ground up, clean sheet design featuring "as-cast" intake and exhaust ports that outperform CNC ported factory style heads, thicker deck surface, dual layer water jacket with reinforced gussets to better distribute head stud clamping load, hardened seats and guides for superior wear characteristics over the long haul, and best of all, the ONLY USA Made aftermarket head available for the 6.0 and 6.4 Powerstroke.
