Being only 6 lobes I'd think you could get more dwell time out of each set of points vs a V8.
My question would be with equal centrifugal and vacuum advance what would you gain vs a good electronic ignition setup? Especially in an A body you'd have 2x the PITA setting up a points distributor, not a real abundance of space down there anyway on that side of the engine to fart with 1 set of points let alone 2 sets.
