Here is my rule. If the bearings were installed and NOT heat cycled (engine started) i will re-use them. If the engine was started, even one dyno pull and i need to take it apart they get replaced.
In your case becasue of the dirt they need replaced. You also need to get a bottle brush and clean the oil holes in that crank. I have seen it many times where the grinder will take the crank out of the grinder, blow it off and bag it. Figuring the builder will clean it, the builder figures that the crank grinder cleaned it..
