[AT] Need valves for MM 335

[joehardy at epix.net]

I'm in the process of restoring a MM 335 and found a severely pitted intake valve. The two tractor parts books that I have do not offer any replacement valves. Do you know of an old Minneapolis - Moline dealership that I could call that might have a set of valves? Any help would be greatly appreciated.
