Well like I said in my first post, I know about these valves on V8 engines, however would like to know whether the same benefits would carry over to a honda engine. (Yes I will rev it as high as I can). Lets say the valvetrain can safely handle 10000rpm, what would Ti valves allow you to do? Or better yet, lets say you can make max power at 9500rpm, where would this shift to?

The valves I want to get retain a tensile strength of 190-200MPA at 900C, the usual Ti valves that I know of go down to about 138MPA at 760C.

You also don't need Beryllium copper seats(Although they are nice), you can get other copper based alloys or a soft iron based one will work as well... it all depends what you want to do.For me to make some copper based seats is not really a problem.
