Clean it up and check it periodically to find the leak.

If you're 100% certain that it's not the valve covers (those are a real problem area on small-block Chevys in general, could be a warped cover not allowing the gasket to seal), check the PCV valve as well as the grommet that holds the sucker in. On a car that age it could very well have dry-rotted. Also, I believe there's some weird kind of breather on the opposite side, check it, too. I'm not trying to assume you're not competent, but check the oil cap itself, it may be cracked or have a pinhole in it, and it would be real easy to overlook.

Hope I was of some help.
