The hose you've pointed out in the picture is for the PCV hose, like you said.
The intakes that were set up for power brakes had a square-ish flat boss on the intake manifold directly below the carb on the drivers side. It appears that the shiny pipe in the foreground of the picture is routed to a fitting at that location. Is that true? If that's the case, then you can put an adapter on that fitting for multiple vacuum hoses. By the way, where does that shiny pipe go to back behind the engine? It's obviously not a fuel pipe, but it looks to be 3/8" diameter.
If there is no fitting there, then the safest way to drill a hole is to take off the manifold, lay it on it's side, and then drill and tap for a fitting. Then you can blow out all the chips with compressed air before reinstallation. Usually a 90-degree 3/8" pipe thread by 3/8" hose fitting is used. You can use 1/4" thread if you can't get 3/8", as the hole is a little smaller. It'll still work.
