1 Cylinder Heads. New USA made high-quality valve springs, retainers, locks, valve stem seals, freeze plugs, glow plug sleeves and injector sleeves.
Valve spring pressure is tested and balanced to ensure consistent spring pressure across all valves
Valves and Springs are New.
Cylinder Head Features:
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. Ra is an arithmetic average of the surface finish.
Pressure test: We already test our heads with this process so you can rest assured there is no chance of porosity failures that can be associated with casted parts. Do the job one time the right way!
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.
We only use the highest quality seats to maintain our quality. These hardened seats also fix the problem of cylinder head cracking that is so infamous with the factory integrated seat.
