Where to hook up vac lines on new carb

[Mrturner1]

So I just got a new Holley 650 double pumper and it's almost 100% installed. I'm hooking up all the vacuum lines and noticed I don't have a spot to plug the vacuum line that comes out of the valve cover into my carb. The big port on the back is being used by my th400 shift module, and I have the vacuum advance in the distributor hooked up to the small port under the throttle blades in front of the carb. I don't have power brakes or anything else to hook up, but the PCV from the valve cover has nowhere to go now. It's the same size as the transmission shift modulator so I can't use one of the small ports. Is it OK to put a T on the back so the shift modulator and PCV share the big back port?

It's my first Holley so correct me if I'm wrong on the vacuum advance being plugged in UNDER the throttle blades on the front of the carb too please.

Thanks for any help
