Nope, no drain in the plug valley. The #3 gasket for it is mostly to keep large pieces of debris from falling into the plug wells, and any liquid which gets caught there stays there until it evaporates (or you sop it up with something). Can sometimes cause firing issues, but there's not much you can do to prevent it other than stuffing dish-rags or something into the plug wells before you hose the engine down.

BTW, if you start getting oil in the plug wells your #3 gasket may need replacing, or it could be the valve cover gaskets.
