Valve covers PVC or no PVC

My buddy has a pair of chrome valve covers for $20 like new. Moroso's with each one having only a raised stem breather. No PVC nipple.

My stock valve covers have the breather on one and the PVC on the other.

Can I use these and if so what do I have to do different w/o a PVC valve.

I do not use a pvc valve on my motor.As long as both breathers are new and free flowing it will not be a problem.Dont forget to cap off the vacuum port under the carb.

Before 69, PCV wasn't used, for the most part. It was added for emissions, for a cleaner combustion mixture,( by placing a vacuum on the crank case vs having it pulse between pressure and vacuum). It isn't a "gotta have" by any means.
