CHOATE 6.0 Cylinder Head – Complete WithoutT O-ring 20MM (for 6.0 Powerstroke 2005-2007)This listing is for 2 Cylinder Heads.
Cylinder Head Feature:
Resurface: We incorporate the use of profilometers to make sure that the smoothness and surface finish of the static area meets the Ra of the gasket manufacturer. This is mandatory for proper gasket sealing and keeps the head gasket from failing.
Hardened seats: 75 percent of heat dissipation occurs through the seating area of the head. This is so important that the valve seat is made of proper metallurgy because it is the conduit to transfer heat from the valve into the cooling system.
