Need input...440 rebuild or not?

If it was rebuilt, it wasnt doen very well. There's crap imbedded in the surface, and the crank surface has contacted the bearing face a bit which tells me the crank's probably not turned well. Bearing crush is not "one time". Unless you dont know how to take them out without damage or the engine has issues of other sorts. What does the backside of the rod bearings look like and what are the dates on them? And the mating surfaces of the main caps and block? I'd like to see some rod bearings.
