It could have been the water in the oil. Hard to say but regardless the wear is odd and not spaced over the whole bearing face if I see it right. That tells me either the crank, or rod/main bore, had issues. As was said, you need to start from the beginning. Was the block align honed? Why would the crank be .010/.020? Was it already cut once? Don't forget the cam bearings. You can't get all the crap out of the oil gallies unless the bearings are removed.
