I need to by Joseph a pint for that unqualified agreement with me!

I do exactly what Bob does with my BT7 except I use a non-resistor plug =
=E2=80=93 Champion N12YC and 0.028=E2=80=9D gap. I too use a Lucas =
Sports coil. I always thought the resistor plugs were to introduced to =
supress interference with car radios, which I don=E2=80=99t have, but I =
am happy to be corrected on that. I think plugs are unnecessarily =
changed too frequently. I remove them once in a while (every few years) =
and clean and check the gaps. I run them until they shows signs of =
deterioration. I have never had a plug fail me in the Healey.

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.=20
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.

1. I was looking through my library of files on Healey topics and saw =
that we were all over the place on plug gaps=E2=80=A6..all the way up to =
0.035=E2=80=9D. So what=E2=80=99s the opinion there??

BP5ES. Was a hold-out for their B8EGV 5627 but that was dismissed =
fairly vigorously by Jeremy Welch as being way OTT for normal road use.
3. And, I have 12,000 miles+++ as plug replacement mileage so long as =
they still look and perform OK. Any thoughts?
