Motor question

Did dry compression check on my 161k L98 engine. 3 cylinders were at 145 and the rest were 160-190. We put in new plugs and new injectors and the engine ran rough afterwards. One cylinder was not firing. I removed the plug and the ground was bent down to the center electrode

I ran the motor with the plug off for a few seconds to see if anything would blow out the plug hole. Didnt see anything so did another dry compression test and this cylinder dropped from 145 to 90.
I put in one of the old re-gapped plugs and the engine ran ok. Sounds like time for a new motor.

Any ideas on what would bend the plug?

If you want stock, rebuild what you have. If you want more power, the options are huge. $5000 wil put together a nice motor.
