Ziptie the cam sprocket to the timing belt and remove, hang from a bungee cord so one doesn't lose timing. Lose the head bolts. Manifolds stay on the head. Both are on the same side. A jack goes under the exhaust and lifts everything an inch or two. Grab the old gasket and quickly wipe everything down with a scotchbrite pad* then slide a new gasket in.
This way you don't have to fight rusty exhaust manifold studs. On a mopar 2.2/2.5, the heads stay good most of the time but the gaskets blow fairly regularly. I was still driving the truck but getting exhaust bubbles in the radiator overflow, a sign of future trouble. Dragging a bed full of firewood etc around with that tiny motor I wanted it in full performance mode.
*evil b/c leaves little shards everywhere, but it works.
