Does anyone have drawings of the intake and exhaust valves used in powtwar Vincents? I found a manufacturer here in the US that will make me valves in Titanium. I have new valves I can send him but would prefer to send him original specification drawings.

I'm pretty sure Steve Hamel's Bonneville bike has Ti valves. He might have some ideas for you.
