Here's an update:
Thread Chasers, at least the one I bought, require a 13/16 deep socket to use. Unfortunatley, a 13/16 deep socket is too wide to fit in the spark plug area.
I decided to not take a chance on the next step (thread repair system), but had talked to a shop that recommended I use one of the old spark plugs, coated in grease, to try to clean out any debris that may be blocking. That seems to have done the trick. I worked it in and out a little bit at a time. While I still needed to use the ratchet to install the new spark plug, it did not require any amount of force at all. Hoping I can use similar lack of force to remove them next time.
Thanks for all the input. I'll upload a picture of the old plugs so you can see the threads all seem to be fine and no corrosion...I have no explanation. The broken diode, on the other hand, may explain why the engine was running rough prior to the swap (at least I hope so - doesn't explain why it only seemed to occur ~6500 rpm).
