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><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).
