The Boyer utilises  standard coils so would assume the output voltage would be similar to a points set up. If a greater plug voltage is generated then the plug gap could be opened up a little to obtain cleaner combustion. I wouldn't close the plug gap and I think the standard gap is more than likely to be fine!
