On my C3 with its 427 I still use a PCV on my valve covers. I like to see the nasty blow by get burned in a car like mine as it runs rich and has a big carburetor. Having a vacuum in your engine will help the rings seat and stay sealed up the best they can.

There was a guy on here last year with a vacuum hose to each valve cover, then to the intake. I asked him how he was introducing fresh-air into the crankcase to replace what was removed.
No response.
I said, you can't run two negative pressure (vacuum withdrawl) lines to a crankcase without a positive air introduction (replacement).
Still no response.
In laymans terms, I wrote, you can't have two successful outlets with no inlet.
STILL no response. I guess he just didn't get it.
