Steve, thats not how I would do it, it can not vent as you'r pulling from both valve covers.
I would, like found on most cars..
A fresh air filter on one valvecover to let the air in ( sometimes found with a hose just before the aircleaner )
A hose with pcv valve to a catch can on the other valvecover so it can vent out.
A hose from the catch can to the intake manifold, at the plenum side, not on one runner.
This way air can circulate, the negative pressure from the intake can pull air through the engine.
EFI engines can correct the air fuel mixture. With carb't engines you can correct air fuel mixture with jetting ( idle jet, main jet, air correction jets ). Thats why we all have AFR gauges on board so we can see whats happening and react to it.
Or do not vent to the intake, but use a PCV pump like found on the Mustang and vent to the athmosphere.
I am running one of those pumps on a V6 with tripple carbs on a individual runners intake so no provision for PCV or brake booster.
