Which is reasonably similar to the factory setup, assuming the connectors on
the carbs lead to manifold vacuum.

Sounds to me like it's due for rings.  That's really the problem with the
factory PCV systems, they don't deal well with engines that are worn and
have significant blowby (combustion gases leaking past the piston rings).

You could add a valve to the line you have, after making sure it leads to
manifold vacuum.  But the valve is only to restrict air flow from the
crankcase to the intake, so it's not going to help with excess pressure
inside the engine.
