Advice for checking junkyard LS Gen 3 what things should I check when looking at LS dropouts?
a local Yard has a few complete 5.3s and 6.0s on pallets
they dont allow people to drop the oil pan, but allow valve covers to be pulled off.

Pull the covers, the plugs. Turn w/ a breaker bar. Watch what is blown out.
If you have access to a bore scope, look in the cyls.
[I use a Snapon unit.]
Water?
Plugs clean?
Under vc clean?
Signs of damage, if it came out of a wreck. Donor vehicle still there?
Check block, head markings.
2005 and up, if possible.

If it turns over smooth and you don't see anything broken under the valve cover, put it in.
These things have six bolt mains and can make stupid amounts of power under boost before breaking.
You see them running 250+ thousand miles under work vehicle abuses pretty routinely.
Buy one and bolt it into place

^ agree with that. if the oil was changed regularly and the pcv was functional it'll be pretty clean. coolant in the oil will sludge it too as I have seen on a couple 706 headed 5.3's and 4.8's. you don't even need to pop the valve cover, just pull the oil filler neck out with a good hard twist counter clockwise.
but then again I have seen sludgemonsters go super cheap and make crazy power.
just get as complete a set up as possible is my recommendation. whatever you dont use can be sold.
