I agree with Lust4speed. Hard to tell in the pics but that caught my eye first.

Couple of the journals also look pretty scorned to me. Much more so than journals right next to it. Enough to make me think the crank may need to be turned. But I'd have what ever it is showing up in the picture checked first, it might be done anyway.

Certainly appears the engine had some trash running through it. From the way the mains look it also gives me the impression that the main bore alignment needs to be revisited again.

Upper rod bearings do have some wear, but not as bad as some I've seen with engines that had known detonation. If this is just basically a stock engine that could most likely be dealt with in the tuning or maybe fudge around with camshaft selection a bit, but I'd be more concerned with the other problems at this point.
