No I don’t confidently, I do have feeler gauges and my grandfather told me 18 intake, 32 exhaust. I’ve watched a couple YouTube videos though and kinda understand it.
Pull the heads and rebuild them. Once the heads are off, there are many other things that are easily checked.
Depending on if the engine has adjustable rockers. They were not adjustable from the factory.

When is the last time it ran? Many times I find aircraft engines in the spring that won't pass leak down when cold, right out of storage, due to those valves sitting open all Winter. We then "stake" them.. read smack the bastard with a hammer to unseat and seat to knock the rust off the valve sealing surfaces. Failing that a run and then they all go back to good.
Yes but the problem should be properly diagnosed before ripping any parts off just yet

the engine runs good just a little funny sounding at idle and old timer said he can hear that the valves need adjusting….he also told me the truck has aluminum rockers
I agree, but those compression readings have valve train issues written all over them, or possibly a timing chain issue. The engine could need a total rebuild, but I don't see finding out without taking something apart to look. Start with the valve covers and go from there.
Hmm.. that says alot. Yes time to lift her skirt
Now you have told us a little more. Yes a valve adjustment could be the problem, or even some bent pushrods. Burnt valves? You will be able to tell more when you get the valve covers off. If unsure post pictures.
