Took the valve covers off...how bad is this?

Doesn’t look all that bad. Definitely has a stain to it, but from what I see in these pics, no sludge! You can clean all that up while your there or run 1 quart of trans fluid with your next few oil changes. 5 quarts of 15w40 Rotella and one trans fluid quart. 1000 mile oil changes. You’ll see how dirty it will be when you drain it. Marvel mystery oil works too. If your really concerned about it, after those oil changes you can drop the oil pan and clean it all up down there. Check the oil pump pick up screen make sure it’s not clogged with sludge. The oil pan has a section where they tend to collect all this sludge, bad design! Then the oil pump pick up gets clogged. Good luck.

I would disagree. The original owner could have changed every 3k miles but dino oil builds up carbon over time. Synthetic doesnt. In the picture below these heads are of of a ls motor with 130k miles, all synthetic and oil was changed every 7500-10k miles.
Every engine ive pulled thats lived on full synthetic is clean as a whistle, regardless of interval.

From my experience oil is not the only thing that builds up carbon. the quality of your fuel also has a big part in this. Changing conventional oil every 3000 miles is key. Using premium fuel, and fuel additives will also help carbon and the deposit build up. I have a C6 Corvette with a fully built LS3 I run Mobil 1 full synthetic 5W 40 change it every 4000 miles, and when I drain that oil it’s dirty not filthy but it’s got a stain to it.

Now would also be a good time to do head gaskets and see if your lifters are dished. You'd be surprised how responsive your truck gets by putting lifters in that aren't so dished. Use a metal ruler and you'll see what I mean.

You should address the wire loom, you need new put on, if you disassembled a little more you could change out your injectors.
