<p class="MsoNormal" style="margin-bottom: 12pt;">I've
run over 150K miles on Champion plugs with nary an
issue (and will continue to do so); RN12YC for the
BJ8 and whatever the recommended is for a 100M
(RN10C?). With Pertronix Ignitors in both, I run
slightly over 'book' value (0.025") at 0.028" and
both run very well (I also run stranded copper wire
secondaries, so the 'R' is important, plus the plug
caps have a resistor in them as well). My one-time
auto shop teacher father maintained whatever spark
was sufficient to ignite the mixture was
adequate--mixture and compression took it from
there--but a larger gap induces a 'hotter' spark
which may be beneficial with leaner mixtures and at
higher engine RPM (but has less margin as the
electrode erodes). A larger gap requires the coil to
produce more secondary voltage to jump the gap; a
sports coil may be required to produce a consistent
spark. 12K miles on plugs is fine in my
experience--as long as the engine is in good
nick--and they can be cleaned and re-gapped at least
once. Sandblasting is a no-no as it will pit the
ceramic insulator and can cause issues. <br>

I came across a YouTube video by David Vizard where
he claims E3 Diamond 'Split Fire' plugs produced
slightly better mileage; yep, E3 makes a plug for
Big Healeys (6-cyl only, I think). I've heard rumors
that counterfeit NGK plugs are in the market.<br>
