If there are dents, these need to be carefully "massaged" out, then install a new gasket and carefully tighten the valve covers - not too tight.

I know I can tighten mine annually, and by tighten I mean with a small screwdriver trying not to dent the holes.
I use the round part of a ball peen hammer to "un-dent" the holes.
The spreader "washer" is a good idea, I may but some.
