Aluminum valve cover PCV

I already have a breather, just need the PCV. I knew that the typical stuff was out due to the stovepipes, that’s why I posted the question.

This is my first car with aftermarket valve covers, and I know how important proper PCV function is. Do these breathers with the nipple function as a true PCV?
Professor Fate showed you the PCV and cap you need for the stovepipe on your passenger side valve cover.
