I've always wondered about this. The 4 prongs, that is. Only one 
prong is going to fire - not all 4. There is no way to know which one 
is going to fire. So, you're right, 4 prongs end indexing, because 
you don't know which gap to index off of.

AND, since you are never sure which gap is going to be fired across, 
you run a higher risk that one of the prongs will actually be 
blocking the path between the firing gap and the intake valve.

No doubt someone will set me straight, but what's all about, Alfie?
