We had a 335 Utility once, but didn't need to O'H the engine. I have other MMs that I have OHed. There don't seem to be complete kits available like you might find for the Farmalls, JDs and Fords. I sourced parts from a very knowledgeble engine parts supply house. Rings, bearings, gaskets, etc were all available. But the availability to find pistons is questionable. On many MMs, you are comitted to using the old pistons or finding other old or NOS if someone has any. For my work on the 206 cu inch (same family of engine, but not OHead valve like yours), the machine shop miked the valve and found with slight modification that the valves from a Chev 350 engine would work.
Maybe find a MM collector guy in your area, and he will probably be glad to share some tips with you, especially as to where to get parts and machine shop service. One of the well respected parts suppliers is Welters of Verona MO. phone #417-498-6496. If a lady answers, trust her knowledge, she knows her parts.
