First I'm going to blast it and then I'm not clear yet what to do with it: Make it black with the BMW-characters and lines (and all other characters like the 'zündfolge' and related cylinder numbers) just cleared and done with a transparent varnish / clearcoated. It should then be looking somewhat like this (found this one on e30-talk.com though this is not a E30 valve cover (those had the BMW-roundel instead of the BMW-characters if I remember correct):
