Engine Ticking

[Dmod81]

All - need your help. My engine has developed a tick. I drove it on Sunday - embarrassingly I did hit the rev limiter. There were no issues when I parked it. Today, when I started the car, I heard the tick. Video is here: https://youtu.be/jiUyyVhvMvk

It does increase with engine rpm, although there gets to be a point where I can't hear it due to exhaust noise. The car does seem to shake a bit. Oil is good and oil pressure is good. I attached my timing light to all of the plug wires, and got only very intermittent flashing on cylinder #6. I plugged in my Tech one, and the R Int is 146 with the L Int at 132. BLM is at 133 for both. Also, the O2 voltages were jumping around a lot.

Is the ticking/knocking noise likely the flywheel, and the overall problem likely the coil?

Thanks for all of your help.
