[Roadsters] Spark Plug Seat?

[Daryl Smith]

Just going over my R16 head and notice that the end of the spark plug is about
.030" to .040" inside the threaded chase at the combustion chamber. On the
sparkplug itself, there is another .030"-.040" before the threads
start.........

Would it be beneficial for power and efficiency, albiet small, to machine the
seat in the head to get the spark that .060" - .080" further into, and closer
to, the center of the combustion chamber?

It isn't till the threads start that it will make a difference as far as heat
dissipation into the head, so the same contact area will be there for
that......

Just throwing out ideas.......
