Default Miss on single cylinder

I have my first XJ Cherokee, a Red 2001. It has a 3 1/2" Zone full spring lift kit, 265 85 16 tires on stock rims, custom fabbed rear receiver bumper with clevises, Rough Country Front winch bumper, with Smittybuilt 9599 pound winch. and roof rack.
I developed a dead miss on one cylinder, and assumed it was plugs since I had no idea when they were lash changed. After changing plugs, coil pack, going to 4 hole injectors, and installing an aftermarket head, and changing out the PMC, I still have the same miss. Any ideas? I have ordered a noid light kit and spark tester to try to narrow down the problem. HELP! I love my jeep and I'm out of ideas on how to fix it

Aftermarket head?
Compression test before anything else.
