From what i've heard the intake manifold has to come off. DEFINETLY spray/soak every nut and bolt on the exhaust manifold at least the night before you try to remove the nuts. WD 40 works well. You can use a wire brush to remove the rust to try to help out a bit.

From experience (not on my wrangler) i know what happends to a frozen header nut and would not recomend it. I will let you think what it is.

spray the bolts with PB blaster everyday foir a week prior to doiing it. exhaust bolts like to snap. if its a 4 banger and its similiar to mine ( i havent looked under the hood of the newer ones) you have tro pull the intake manifold. its fairly simple with the exception that on mine, the replacement manifold support skirts interferred with the intake manifold nad had to be ground down some.

edit. i just see where yuou have the 4.0. so none of that probably helps. PB Blaster is good though, make it your friend, use it.
