are you looking for what air cleaner components or a valve cover breather 

the valve cover breather is the same regardless of engine/SHAKER & is 3-nipple for all '71 'cuda engines

[Ric]

figured it out, yes valve cover breather , and yes now I know its  a 3 nipple, but where do all the lines go.....

[RUNCHARGER]

Yes: 71 means 3 nipple valve cover breather.

smallest - vapor return line that's bolted to the inner fender
middle - fuel bowl of center carb
largest - usually goes to the air cleaner, on a SHAKER it's on the adapter ring

They should be like this... (Thanks to @ScottSmith_Harms for the photo)

What about for a 1970 440 sixpack?  My center carb does have a vent tube, but should there be 2 or 3 nipples? The vapor return line on my car comes from the vapor separator by the fuel pump.

Your 1970 440+6 will have a one nipple breather connected to the air cleaner...that's all.

Alan, so should I just plug off the vent tube on the center carb?

You have the wrong center carb, I would just leave it open or get a two nipple breather cap like used on an AAR or TA  and put a hose running to the carb. I don't think I would just "plug" the vent
