I was going to put this in my thread about larger valves, but I couldn't find it. So we get a new thread.
I made some drawings of the stock intake and exhaust valves for anyone that wants to order custom valves and needs the dimensions for stock. When you send these to whoever is making the new valves you should specify how much diameter oversize you want, probably either +1mm or +2mm. Any more will need serious head modification.
