Airworx in Alabama is my go to shop now. I sent some questionable A65 parts and now have beautiful overhauled parts. Wish I had known about them before having my AEIO-360-B1G6 for the Great Lakes overhauled. Could have saved some serious money. Yes, they have the process to build the crank back to standard.No. It would be the same as a C-90 or O-200 with reground crank. But somebody in Alabama has been approved to bring crankshafts back to standard, so that’s another approach. I think the .020 under is STC’d for the 85, and you can combine STCs if your mechanic finds them compatible.
I take it they can take a non-nitrided crank back to normal? I measure cranks before I send them. Have had the crank shops want to grind but then when I told them the measurements and that they fell within tolerance they relented. They like grinding them, more money for them.
That's been my experience as well. Aircraft Specialties just flat out lied about wear and runout on the last crank I sent them. According to them, everything was worn out. My measurements showed everything to be within sped on only in need of a magnaflux and polishing. Along with other bad experiences with them, they have become my last resort for machine work.
I just had a C-85 case overhauled by Airworx, then converted from a -12 to a -8 by Don's Dream Machines. I haven't done a close inspection yet, but what I have seen so far sure looks nice.

When you get older you will regret not having the dash 12. I can still solo prop at 82, from behind, but the day is coming when all starts are push-button.
When older folks ask me about Cubs, I insist they hold out for a dash 12, even at a premium.

I saw paperwork putting C-85 cylinders on C-65’s there’s directions on how to mod the cylinder holes on the case.
Just trying to counter the desire of purists. Len used to tell folks how horrible the dash 12 was, and because of that, two Cubs now belonging to old folk are not flying. I can help them start, of course, but they are a ten minute flight away.
Near as I can tell, the dash 12 adds four pounds or something - hardly a major hit. Sure, checking the screen is a wee bit messier, but it really isn’t bad if you have the right trough set up.
