It is not too hard you just need to keep up with where everything came from. When you remove the spark plugs wires it is especially important you put them back on the way they came off.
You are lucky to be working on a V8 as there will be no issues with room or having to get into a really tight place.
Do not overtighten valve cover bolts as they do not take much to tighten and a little silicone to help the seal would not hurt.
