360 vacuum leak.

Well I didn't want to run it like that but I was trying to see if my vacuum leak went away if I either (A) just ran two opposite breathers, or (B) ran it with pcv one side and breather on the other. I couldn't do option b because I had nothing to plug the breather hole with at the time. I'm just confused by the outcome because I've seen engines run with just the two breathers.

Just because you've seen it, doesn't mean it's right. Have you tried a squirt bottle of water around the carburetor and intake gaskets? Don't use something flammable like brake cleaner or carburetor cleaner, because you're literally spraying gas on a fire.
