THEN from there a 2nd larger pcv hose is attached using another grommet and some type of fitting into the top of the passenger side valve cover baffled hole and out, this 2nd hose is attached from the valve cover to the base or side of the air cleaner which completes and allows the correct circulation of pcv system. These spent gases should travel through a spark arrestor before exiting into the carb.
You can also install into the valve cover push in filtered breathers as typically seen on modified engines.

You don't understand how a PCV system works. The connection from the air cleaner to one valve cover is for filtered air into the crankcase. This air and whatever vapors and blowby gases are drawn through the PCV by the manifold vacuum from the hose running to the base of the carburetor. Crankcase gases are never intended to be drawn through the carb, and in fact this only happens on an engine with excessive blowby.
