I am looking for an after market air breather for my stock gm valve covers that will keep them looking stock (no chrome). The hole opening is only about 3/4" and I know that I can hook up two PCV valves but would perfer not to.

Has anyone else ever used 2 pcv valves?Is this a poor mans version of a vacuum pump to prevent ring flutter.I would think you would want filtered fresh air being pulled into the base in a street application.
