Need help fixing my Carter carburetor 4298s.

I've learned quite a bit rebuilding and fixing my Carter carb. It appears as if I need to replace one of the ports/connections where the PCV hose is routed. I looked at the hole closely and it looks like there is a small lip near the back of the hole. Possibly that is what the port bottoms out on after its pressed in? Can anyone please tell me where I can find the right size port to put in there and is it pressed in? Also is there supposed to be a hole in the front right side of the carb that runs to one of the primary venturis? Please take a look at the pics and let me know.
