At the last annual, my mechanic showed me how to anneal the copper spark
plug gaskets before reusing them.

Is this common practice?

I don't know how common it is but it's done and it's not that time
consuming.

Mount a steel shaft horizontally in a vise and slide the gaskets to the vise
end. Below the open end of the shaft place a coffee can full of water. Slide
the gaskets out to near the open end of the shaft, heat them red, then slide
them off the end and they fall into the water.

Including setup time you can do 100 gaskets in about 10 minutes.
