Very Rough Idle/Multiple Codes/Debris in Cylinder 4

[synyster]

Still have no idea whats going on. That's why I turn to this amazing forum lol. The other night I blew my bypass cap behind the throttle body, coolant got all over the engine compartment. Leaving it on the side of the road was not an option because of the neighborhood it was in. I didnt want to come back sitting on rotors and missing all my windows. So i tried to make it home all ws going good until it started to overheat.. once it started to overheat I immediatly shut it off and pulled over. I let it cool down and added more coolant. coolant got all over Including coil packs and all other electical things. Yesterday I kept getting codes P0207,P0304,P0307, P0300. I pulled the 4 and 7 plugs and 7 had oil on it, and 4 had oil and what looked like paper or rubber that was green on it. I have a very rough idle that shakes the whole truck, and it's dumping unburnt fuel into the exhaust. I was also low about 2.5 quarts of oil.

I'm leaning towards blown head gaskets and jacked up coil packs and plugs. I know my valve cover gaskets need to be replaced thats where all the oil is coming from.
