Ignition coil voltage

Hi,

My Pantera's ignition consists of a 'Duraspark' D5AE 12A199 A3D with a green strain relief, the gigantic Accel Super Coil 140001, and an external ballast resistance of 1.6 ohms, all powered via a 12v relay....

Pantera - ignition, starter

I have recently fitted the 12si alternator kit from Pantera Electronics and now have a battery voltage of ~14v. Now, the 'Duraspark' module has ~14v at the red wire connection, and when idling the coil +ve has ~9v. The voltages before were ~13v and ~8v.

My questions are;

1. Will that voltage be OK for the coil?

2. Is there a better, more compact coil? You can see how cramped everything is.

3. Is a spark plug gap of 0.050" ok?

I realise that this may not be a Duraspark (II) module due to its 1975 year of manufacture, I'd just like to not ruin the system and optimise it further if I can.

Any assistance will be greatly appreciated.

Thank you
