@318willrun has a video which illustrates the plug hole issue and how he addressed it.

I fully agree, however I am not in a position to redesign the existing combustion chamber. This was just an idea I had while
inspecting my old plugs from my truck and was looking for feedback on. Ideally the spark plug entry to the combustion chamber should have been spot faced to eliminate the plug being sunk/shrouded.
That plug will certainly help to better place the spark event into the chamber and would be an improvement.
