I put it on yesterday after flushing the engine out really well.the oil pump is clean and nice looking. the gears are tight like they are suposed to be and the pickup tube and screen are clean. if the rod bearings are good looking as they are, should'nt the cam bearings be the same.....or could the cam bearings be scored and not the rod bearings. i'de think if the cam was scored then the rod B would be also but im far from mechanic status........

If the shaft is OK and it turns freely and the gears don't have much backlash it is probably fine.
That being said, unless you checked the oil pressure with a mechanical gauge prior to pulling the pan and the pump you're shooting in the dark.
