Changing a 75 to an 85 is simple. Change the carb jetting and remark the dipstick. You will also have to change or repitch the prop and remark the tach Continental will not issue a new data plate however but there are several sources where they are available. Starter and gen require no change. From my perspective the best move is to replace the innards with 0200 crankshaft ect. Major improvment in performance but a bit pricey

The TCDS of the plane tels you the starter and generator are no longer allowed, i.a.w. note 308 and 107. The TCDS of the plane does, as far as I can see, not give any replacement P/N for both. The TCDS of the engine states the same starter P/N for both engines. Also the P/N of the generator is useable on both engines i.a.w. the engine TCDS although, if I had to change it, I would go for more capacity or probably an alternator. I am studying to be an A&P, only have the practical exam to go, but even I am lost here. Who can help me out?
