[QUOTE="Rolls, post: 205382, member: 28"] If you switch to stainless valves, then you can use the stock seats. The seats will need to be re-cut though. The stainless valves are heavier than the stock titanium valves and need a different spring. Also, some performance is lost because of the added weight. If you use the stock titanium valves then it is advised to switch to beryllium seats. The stock seats are too hard for the titanium valves which results in a short lifespan for the valve. I am not aware of any updated products by Honda to fix this problem. No matter which route you choose to go, there is specialized machining that is required. If you don't have the tools or the know how, you're better off going to a pro. These guys have been around and have a good reputation: [URL]http://www.fastheads.com/[/URL] [/QUOTE]
