None of the bolts were frozen on mine and I felt they came out easily. However, I have heard of the bolts shearing off, mostly on 4th gen trucks. If they shear off and stick out, just use channel locks to unscrew them. If they shear off flush, weld a nut to the bolt with a mig welder and turn it out.
Below is the torque spec for the exhaust manifold bolts. Although I think it might be easier to time travel, than get a torque wrench in there to tighten up header bolts. I even modified, (bent it with heat), an open end wrench to make it easier to reach a couple of the bolts hidden behind header tubes.
This video is a for a 4th gen RAM header installation, but it's basically the same procedure.

- Right Side: Using the sequence shown, Install the exhaust manifold retaining bolts and pre-tighten to 25 N·m (18 ft. lbs.) allowing the gasket to seat to the exhaust manifold and cylinder head.
- Re-check the torque at 25 N·m (18 ft. lbs.) using the sequence shown.
