Leaky valve cover gaskets. Oil getting on them. Are they newer or painted?

they did have oil on them. so i cleaned them off the best i could but when running it atill smokes. do you think i should tighten rocker arm cover bolts more then let the it burn the oil off on its own?

Look for where the oil is coming from. Honestly if there was oil on them, I'd just go an replace the valve cover gaskets anyways... they aren't expensive and it shouldn't take too long to do. then when its cold get some engine degreaser and clean off the manifolds.
