Look at the valve seals to make sure they aren't cracking, look at the valve train to see if there are any irregularities, see if any sludge is building up (water in the oil and or excessive heat), replace the PCV valve, and check the oil return holes.

Basically it is all visual inspections and won't take long.

Only thing I know of is to lay them on a some glass to make sure there flat.I don't know about Fel-pro Morpar gaskets but the blue ones for Chevy you don't have to glue them.

Everyone has a different method for gasket application and here's mine. I will douse a rag with brake parts cleaner, with proper protection, and thoroughly clean the mating surfaces on the heads. Brake parts cleaner leaves no residue and will get all of the oil out of the crevices. After checking the fit of the gaskets on the valve covers I apply a light coat of Permatex#2, set the gasket in place, put bolts in the holes on the valve cover and hold everything in place with plastic clothes pins. After about a half hour remove the clothes pins and the bolts and slap the valve covers on. They won't leak and the gasket will stay in place if you have to remove the valve cover later.

A good look around for heavy sludge is always a good thing while you have the covers off.
Other than that if you are not having any issues leave it alone. More people get in trouble fixing things that are not broken. You can find many threads here that start with "my car was running fine but I wanted to adjust" and the next sentence explaine that it no longer runs correctly.

the old adage, if it aint broke, don't fix it applies

I've always thought it was important to not over-tighten the bolts and distort the cover, thus causing a leak.
