new engine or stroker kit?

Like Wildcat said its hard to tell by the pics but the crank don't look that bad I've polished up worse then that with crocus (sp) cloth.

As long as your bearing crush and clearances are good you should have no problems, the bearing shells need to be pressed into the journals if it just drop in and falls right out then you might need to check to see if the journals are out of round or oversized or not.
