I recommend getting a factory manual and following the recommendations there. Measure everything and if its in tolerance let it be. If not follow factory recommendations. It is quite possible at that mileage it could be fine to use as is and just replace seals and gaskets on the bottom end.

Or it could have been gone through already. I'd have measured taper and bearings before taking it apart.

Cam chain guides and oil pump chain guides along with new chains if needed.

And look at the head. Since its out I'd prob do a valve job. again, measure things and if they're in spec reuse. If not replace.
