Home cities currently start with 8,500 rescap, 160 huts would only add 16,000 to rescap, plus any bonuses from Traits and Techs.
These are subject to change, but currently Orc buildings provide this much storage/resCap:
Huts, Pyre, War Hall and Ogre Pit = 100
Goblin Tents = 200
Armoury, Warg Pen and Temple = 400
Guild Hall = 500
Warg Pens are usually the best option to build as they give high rescap and produce all those Wargs
