We went to a few suppliers to get the best quality for these manganese bronze valve guides. Made for better valve support at high temp, RPM and load. For those with bigger valves, bigger cams, heavier valve springs this is what you need to increase durability. These were designed and made to exceed CW713R spec.

Manganese bronze valve guides are a popular choice in high-performance engines due to their exceptional wear resistance, high-temperature strength, and inherent lubricity. These properties contribute to extended valve life, reduced friction, and improved engine efficiency. Additionally, manganese bronze's ability to maintain its shape and integrity under high-speed operating conditions ensures optimal performance and durability.
