Eric---I wonder why it is, that the late model head with its lower
compression would call for the colder (N9) plug? This is the plug that
caused premature fouling in some of the early  seventies engines. Do you
remember the source that recommends this heat range for the 75-76?
Also, a "shorter" plug could expose the sharp corner in the head near
the tip of each plug, creating a hot spot.
