VALVE GUIDES
Pick the Valve Guide that can stand up to the heat!
Maganese Silicon Aluminum Bronze is by far the most superior valve guide material available today. It's tough and ductile, to resist cracking and corrision. It also reduces friction and insures high lubrication retention. And it retains these qualities at today's elevated engine temperatures.

VALVE GUIDES - HARDENED VALVE GUIDES
Premium quality cast iron(alloyed with chrome, moly, nickel & copper) and heat-treated to Rockwell 30 "C". Incorporated into the guide is a spiral-grooved lubrication design, which produces the ultimate in wear resistance. This is far superior to any guide material available. It is a proven material, that has been used for years in severe, heavy, or high duty applications. They are the perfect choice for engines prone to wear due to high combustion chamber temperatures. These guides may require reaming or honing for slightly more stem clearance(.0005" to .0015"). We recommend using a wider valve seat contact angle, to cool the valve and reduce stem expansion: Min: .080" to Max: .120" seat width. Add an I.D. Chamfer(approx. 1/16" x 10 to 30 degrees) or counterbore to the I.D. of the combustion chamber end for scuff/seizure resistance.
