It's the standard since the invention of the piston engine. - C630 bearing bronze. A tough nickel-aluminum-bronze alloy typically used in high performance and racing applications where rapid heat transfer from the valve to head is important. - Manganese bronze. Softer and less durable then C630 bearing bronze but will allow a lower cost and reaming to size is quick and easy. Finish can be done with simple tools like a ball hone and an electric drill. Rapid heat transfer and excellent lubricity. Note: Special Manganese reamers & hones are available. Kibblewhite Precision Machining Inc. - Valves Guides STD size: 0.5650" O.D. (14.35mm); 0.3085" I.D.
