Crankcase breather catch cans

Not sure if this would work with a header Evac system but I just bought one of these universal Moroso air/oil separators. Moroso 85497 It's not cheap but it's a quality part for sure.

I haven't installed it yet so I can't say how it works at the moment but the concept makes sense. It's filtered and comes apart to drain the oil and clean the filter. Mine is a street/strip car so I'm going to use a PCV valve but I don't think it's a requirement to use one with the separator.
