1. In addition to possible damaging stress on bolts and nuts, overtorqueing can also distort sizing and geometry. I strongly suggest you redo anything incorrectly torqued.
2. The aluminum crankcases are not overly dimensionaly stable. If properly done, when the main bearings were align-bored, the crankcase was properly fastened to the cast iron cylinder block to insure trueness. The same should apply when torqueing the main bearing bolts, bores should be attached to the crankcase first.
