Is this right?

[Chevy nutcase]

I was finishing up the plumbing on my new power brake setup and the booster just touches the air cleaner so I'll have to get a smaller one. No biggie but I noticed the valve cover vent isnt hooked to the air cleaner since its piped right to the intake. I didn't think that needed that much vacuum. Am I right thinking I'll hook it to the new air cleaner when I get it and plug the intake port?
