This is what Tomei has to say about their Valve Guides. Since Phosphor bronze (Cn-Sn-P alloy) has intensity and high thermal conductivity, it is used for the valve guide of high rotation and high output engines. Moreover, since its sliding performance is higher than standard metals, clearance around the valves can be made smaller and operation/setting accuracy can be improved. As a result there is less stress in the valve system, valve stick prevention is increased, and valve guide cracking is less likely.
