IIRC, when I swapped my valve cover for a metal Contour version, the gasket on the plastic unit had a gasket dressing of some kind on it. I removed the old gasket to clean everything up and it had a black tar-like substance on it. If the old gasket isn't torn or cracked perhaps you could remove everything, clean it up and apply a black RTV gasket sealer/dressing to the valve cover and the head. I also had a leak with the metal cover and I used Hylomar to seal it up. (BTW, I may be able to get you a metal valve cover if interested).
