Description:

Kill Devil Diesel is proud to present our  7.3 Ford Powerstroke cylinder heads, machined on state of the art CNC equipment, hand assembled, to deliver top shelf performance and reliability.  

KDD performs all machine work in house on state of the art equipment.  These heads receive all new hardened valve seat inserts, and iron matrix valve guides, as well as all new USA made valves and springs.  We also install Stainless Steel injector cups, standard - to prevent the common factory style brass cup failures.  After being carefully qualified to ensure only the best quality castings are used (magnetic particle inspection for cracks, pressure tested for leaks, treated in our rust removal process, all threads and gasket surfaces are inspected) heads then receive an industrial-grade, heavy duty valve seat profile.  Heads come standard with new valves and springs, with optional 21-4N stainless nitrided valves available for added durability in the most demanding applications.
