If you've never done a valve cover gasket before, a few tips:
-Don't forget the spark plug tube seals. They rarely leak but most gasket sets come with them. Might as well while you're in there.
-Clean the surface of the head where the gasket will sit extremely well before doing anything else. Don't leave any oil residue or anything on it if you can help it. You want a clean, dry surface. Little brake clean on a clean rag/paper towel for a final wipe, maybe. A razor blade comes in handy for getting old RTV off. Don't leave any of the old RTV behind.
-Anywhere the factory had RTV, put RTV. You can almost always tell.
-Sometimes you need to put a little RTV (like, a very thin skim) on the valve cover side of the gasket to help hold it in place when you go to reinstall it. You can just put a tiny amount on a few spots and let it set up for a bit. Nothing like flipping the valve cover over and having the gasket fall out.
-The bolts take very little torque. I use a small 1/4" ratchet and aim for "snug".
