Why not just buy a new set of the stock valves? Getting too custom with valves can be bad, as you will likely grind through the case hardened layer and expose the heat intolerant, rust prone, softer steel underneath.... unless you have an industrial style heat treat shop at your disposal. Then it could work.
How do you plan on making your lower end handle revving to 8K RPM? And you're aware that the fuel cut is at about 6250 RPM, right? Even revving to 7K (if you haxored teh ECU) would be a no-no on a stock crank and pistons.
