Iron matrix valve guides are honed to size for excellent lubrication and oil retention, as well as maximum consistency in guide diameter, ensuring longevity. Additionally, guides are made with higher graphite content, which is a lubricating component
Our upgraded heavy-duty castings, thicker than OE, ensure worry-free service for hundreds of thousands of miles, with both valve stem and guide enjoying a solid lifespan
Pressure tested at 50 PSI and 210F and vacuum checked. Blueprinted to proprietary valve train geometry, to alter valve height and valve recession for maximum reliability and longevity. The Valve stem heights are altered by us to remove preload on the lifter, decrease wear, and help ensure a long life for the lifters.
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.
We already test our heads with this process, ensuring there’s no chance of porosity failures common in casted parts. Do the job one time the right way!
75 percent of heat disappears occurs through the seating area of the head. It’s crucial that we use proper metallurgy for the valve seat because it serves as the conduit to transfer heat from the valve into the cooling system
We test and balance the valve spring pressure to ensure that it remains consistent across all valves.
