Decided to spring for some custom valve covers from SDS. These are very nice billet aluminum with black anodize. I was able to choose a graphic and went with the Aeropsort logo to match my engine. The other big plus with these covers is they have an o-ring groove around the flange where you install a Viton o-ring. This replaces either the leaky cork gasket or the optional silicone gasket that squishes out once pressed.
