What do you think of my bearings...

What do you think of my bearings...
Okay, I pulled the crank out today, and took a look at my rod and main bearings. The surfaces on the crank for the rods and mains look great. The engine had 51K miles when I pulled it apart (it was out already, and needed a rear main, and a cam (well, I guess it didn't NEED the cam... ) so I decided to do bearings while I was at it.
This is the number one rod, and the center main. There is just a slight wear on the rod bearing (on the rod side, not the cap side) and no other apparent wear on the cap side. The main bearings all look almost new (to me, that's why I want your opinions). All of the rod bearings have the same wear there, on the same side. The bearings illustrated are what all of the rest of their respective types look like.

So, is this normal wear for 51K miles? Everything seems to be on the tight end of spec, and I'm just doing an OEM rebuild, nothing fancy. Federal Mogul bearings on the mains and rods, and GM bolts. I've got a good torque wrench and an torque angle gauge, which I think should be all I need.
Any other tips as I head into this?

I prefer Clevite bearings over Federal Mogul stuff though.

This engine won't be anything too crazy. ~375 RWHP N/A with H/C and probably a 75 shot used VERY rarely. It'll get maybe 2000-3000 miles a year.
