250 inline help. carb question. pics.

I have a 72 blazer with the inline 250. Just got a orig 1 barrel intake and a remanned rochester monojet carb. (It had a offenhauser 4 barrel with a holly 2brl. setup wasnt working.) Im trying to figure out where to hook up my vacuume lines. in the first picture i was thinking. PCV valve line from the valve cover on the left, vacuume advance in the middle, and vacuume brake line on the right. That is the only lines i believe i have. Will this work?
Also there are two small lines comming off the side of the carb and i dont know what they are for. Can i just cap them off?

Thank You.

Re: 250 inline help. carb question. pics.

thanks fior the imput guys. its a 2wd 3spd on the floor. fresh motor fully redone 20 years ago and not run since( except for a few times within the last few years.)
alex, where do those vacuume lines go that split into a tee? is all i need the pcv/valve cover line(dont know the term), vac advance and the vac brakes?
just wanted to make sure i hook em up correctly so i finally turn it over again. pretty excited to see how/ if this totally diferent setup will work!

i got plenty of pics. its on a lift for the winter to finally finish it so i can photo anything. anything in particular u want pics of?
