Speedmaster spark plug holes improvement??

I am not sure I would "sink the plug" to try to correct this. I think if I was actually going to do something......besides nothing, it would be to go ahead and dress the inside edges of the spark plug hole so that the end of the plug is completely exposed more like Bobzilla's first picture up there ^^^^^^ . I think that would be the "more correct" way to do it, IF you decide to address it at all. In the end, as long as the plug can start the fire, what difference does it really make? None, "I just bet".
