What is the valve stem dia., length and face dia. for both the intake and exhaust valves of the OM603 engine, also what is the cylinder bore? This may be a doner valve for the OM617 engine, I won't know until I get my fingers and eye's in the ports. If I can't find a bigger valve from the 603 or any other engine we can always work the troat and valve to pick up some flow #'s, I don't want to take too much margin away but as robust as Mercedes are there is probably somthing left on the plate.
