any performance differences in the location of the plug when cutting the top of the head to lower plug into compression area.

If there was an advantage there would probably be a new rule against it. I guess some guys are doing this to cheat the 11CC rule, impetuous.

I have no hard data but I do know you need a big increase in compression before you feel it in the seat of your pants coming off a turn.

You only get to extend the plug about an 1/8″ before you’re trapping air with the tech tool. If you use an extended tip plug it’s dang close to the piston. It’s easier to strip the head at the track.

I go for a clean bee hive combustion chamber centered on the bore for maximum fuel burn because, I know that works.
