Mag or electronic ignition.

I'm going with 16 volt battery for this reason. I have been told by lots of folks it will spin considerably faster. Now if you had to add weight 2 battery would spin the crap out of it but thats about 75 lbs total so probably not good thing.
We ran NGK 9 plugs in funny. Im pretty sure but its been good while.

Do you remember the Gap?

Im sure there's cpl out in shop I'll look around tomorrow.

The MSD looses it's edge above 3000rpm, and the Mag really shines above 4000 rpm and at high cylinder pressures. It's a combination of amps, and duration of spark that makes an ignition system, and without an alternator, the MSD doesn't have the same juice at the end of the day.

It's boiled down to these two questions.
How does the MSD perform with a 16 volt battery compared to a 12 or 20 amp mag. In a blown alky engine combo.
If the ignition system will support it, will increased spark plug gap make more power.
