Beautiful, Mike! You are a Godsend!! :)
No need of a PCV valve with this carb incorporating a "graduated orifice"
via the emissions tube upstream of the butterfly. "Other side" of this PCV
system
is a vented oil filler cap for crankcase inlet air (as you said, Mike. You can
feel the suction at the oil filler neck). The old stock filterd plasic cap will
do with the stock valve cover.
Still a reasonable price for this excellent carb. BTW. How refreshing! :)
Sounds like the way to go Jim Johnson?

Jim,
APT sells the carb you need (same one I bought from them) for
$329.00. All you need is a stub stack (part no. MSS44) $32.50 and
put your K&N filter on it. Block off the balance tube and put vacuum
advance on the port fitting (behind the piston cover, see link)

A spacer is only 20 bucks and you are in business. I have no PCV valve on
my car and only have a vent tapped into the mechanical fuel pump boss with
a 1/2 inch brass fitting, a rubber tube and a small cylindrical K&N type
filter. You can actually feel a slight suction when you put your hand
over the oil filler neck on the valve cover when the car is running. If
you want to go for the performance option, APT will build up an epoxy ramp
in your carb intake throat per Vizard for cleaner air flow into the
manifold. A slight ram effect. I can bring it with me next month if you
buy it to save shipping.
