Default Modified cox 049 glow head
I would agree with Wild Fred, make the counter bore deeper to get the plug flush with the inside of the head.

I have tried this several times over the years and found the performance to be below that of a stock Cox glow head, less RPM. I don't know why. Although they are cheaper to replace.
