5.3 Valve cover reseal

So I’m about to do my first non practice valve cover reseal, my girlfriends 07 avalanche with a 5.3 has a valve cover leak by the looks of it so I am gonna fix it, I’m a Lube tech at ford and I did auto classes through the entirety of high school (class of 2025) so I know what I’m doing for the most part…replace the rubber grommets and gaskets, retorque to bolts opposite of the previous one, add sealant in OEM specified places mostly the corners and not to much or it’ll leak, clean the bolts and I would imagine blue tread lock on the bolts going back in? Any special tips or tricks or steps I’m missing?
