Not sure how cheap is cheap, but I was able to get a valve job gasket set from one of the online chrysler parts dealers (OEM mopar gaskets) for about $75 and it had everything in it - head gasket, intake/exhause, egr, thermostat, throttle body, even the ccv tube. Didn't have a valve cover gasket, though, got it at NAPA. That was almost what just the head gasket was everywhere else.
While you've got the head off, you really should take it to a shop and have it magnafluxed and/or pressure tested to make sure it isn't cracked.
The rest is all labor, not a terribly hard or lengthy job - you'll probably need some help to pull that long hunk of head off the block.
If the head bolts have been reused already (should have paint on them if they have, don't use them again. Go to headbolts.com and get a new set.
Assuming the head isn't cracked or a valve seat burned, you should be able to finish it up for under $200.
