Mission accomplished, PB Blaster and turning it in and out finally broke it loose. No thread problems. Lots of carbon buildup on the threads which kept it glued into place. They are definitely the original plugs. I went to pull the distributor cap and after snapping one screw off in the distributor housing
I pulled the wires off and found this! Original cap, rotor, plugs. The coil wire was burning it's way into the cap! The rotor is so burned it's amazing it ran so well and passed tailpipe emission's! There are 2 screws that hold the cap on so I'll try to drill out the one that snapped but it should be fine with 2 screws. It's amazing that people don't do any maintenance on a car.
