Jeep Wrangler JK (3.8L) Misfire Part 1

Initial problem was a P0300 (random misfire), C121C (Torque Request Denied), and a Catalyst error (don't recall exactly which one). So first things first, we have a history of damaged plug wires (because of crappy stainless headers) and I did in fact have another melted wire so I replaced the plug wire on number 4. When that didnt work, I then replaced plugs after seeing that one was bad and after failing to fire, I had an arc jumping around/through the boot and to the head. I replaced the coil pack, crankshaft sensor, camshaft sensor, map sensor, all four O2 sensors, and drilled out the top two catalytic converters. Nothing worked. At this point I went in and spoke with my local service manager and told him that because of the C121C, I was leaning toward a PCM failure. He thought I had a blown head gasket and after a compression check I did have 50psi on number 2 cylinder (should've been ~175). Since I was planning to rebuild the motor in the winter anyway, I went ahead and tore it apart. That's about where this video picks up. I've got the motor torn down and found that I had both seized compression rings on number two cylinder as well as a seized lower compression ring on number four cylinder. Now it's time for reassembly to see where I'm at...
