The chrome valve covers may be too smooth on the gasket surface area. I would rough it up a touch with a wire brush, clean both surfaces with brake cleaner on a rag and try it again.
I personally use a light touch of gasket sealer on both surfaces. The blue RTV seems to work well for me.
I normally seal the gasket onto the valve cover and let it set-up for a half hour or so before installing.
I only use cork gaskets though. That might make a difference?
