there are special "high heat" engine paints that is what ur gonna want to look for, get whatever color u think will work best 1 bottle will be more than enough, while ur at it pick up some rtv silicon, 1 tube will also be more than enough, once u get home remove ur valve cover by undoing the 4 little nuts and using a soft blow hammer or hammer covered with a towel/shirt/etc. softly jolt the valve cover out of place and remove it, (common sense ur gonna have to remove ur spark plug wires and the ground wire holding it in place so u may want to disconnect ur battery b4 u start ripping things out of place but it isnt really necessary. once u get the valve cover off, clean it all up inside and out, paper towels will be ur best friend, then lay it down and paint away, u can cover with some high temp clear coat if u like but not necessary if u dont want to, then reinstall after cleaning up the old gasket material, reuse the old valve cover gasket, and put on more silicon all around the gasket, make sure u dont get any foreign particles in ur engine. u may want to tighten those top 4 bolts with a criscross action to torque it down with the same tightness on all corners, drive it around for a few days check for oil leakage around the gasket and if there isnt any u did a good job if there is oil leakage u suck at seals and do it again, but rtv silicon comes in decent sized tubes so u'll have tons to spare, good luck and let me know if u need more help
