welcome, jordan.
i would recommend all of the listed ideas, but you may want to pull the head anyways to check for:
A: rusted cylinders, there is a point where it will have to be rebuilt, or it may be workable
B:scored cylinders, this should be addressed by a just honing the cylinders. otherwise, the lubrication will not work right and something will fail prematurely
C:crap in the cylinders, my big truck had the plugs left out for the last 40 years outside, and something used the engine for an outhouse. i would have to guess crap does not make a good lubricant in an engine and should be removed. also good to check for hardware dropped inside, read this about that: http://www430.pair.com/p15d24/mopar_forum/showthread.php?t=21311&highlight=piston
D:chances are, the valves will be sticky after sitting. this is easier addressed with the head off by turning the engine and tapping down the stuck ones lightly, and they will free up faster and it will be something you wont have to do later.
E:carbon in the cylinders, isnt a huge issue, but good to take care of
BTW: if you dont already have one, a handy 3/4" drive socket set is available at menards for about $45 that contains a ratchet, breaker bar, extensions, and all needed sockets except 1 11/16, which is available at carquest for $10. these may be cheap tools, but they are great to have on hand and they have a lifetime garuntee, just like craftsman, but a little cheaper.
