Just pulled the valve cover to replace a gasket and saw that I have valves that are covered in oil sludge. What could cause this? Is it worth addressing? I work from home and have limited resources and knowledge. Any information would help though! Pictures attached thanks!

I’ve seen worse I would install the gasket and cover and roll on.
 
What you see is typical on a old slant 6 engine. There is not much oil up there like a hydraulic lifter motor. Do not worry about it. Adjust the valves and put it back together.
 
Contributing factors.
1-Lack of oil Changes.
2-Short runs. No heat to burn off the condensation.
3-Low RPM'S and most likely slow conservative driving.
4-Design. That is a big box area so lots of moisture can accumulate.
5-Lack of oil. Again design. If there was a lot of oil it would of helped wash the upper end down.

Like I said above do not worry. You could use a shop vac and try to suck off the crud. Wipe it off the best you can. DO NOT wash it into the pan. Adjust the valves. Drive it more and longer to build up heat. Start changing the oil more often.
 
If you think that's bad,guess what your oil pan looks like.
It's a Slant as long as it has some oil it will run forever..
I left a comment in your other post.
