This reminds me of another question around bearings:  was it 20K miles or 50K miles that it is recommended to change the rod bearings after a rebuild, using of course the original size you used for the rebuild?  (I suppose that it would make best sense to ensure you use the same brand too, in order to accommodate any very minor differentiations between them?)

Main bearings aren't touched, right?
