Id put money on it being an electrical issue. If you run a search for misfire on this forum you'll find a million posts with very few solved cases because it's always electrical and electrical is a PITA. I traced one down for months and it ended up being my coil rail but it could be anything. My guess is during the blown head, you overheated and melted some wires or sensors. Do a visual inspection and if everything looks good. You'll have to do some electrical testing on a bunch of different sensors. youtube is going to be your best bet for learning how to electrical teat. Get a factory service manual, it will help you figure out how to to interpret your readings. Not sure what year your Jeep is but start at the spark plugs and work backwards from there.
