/6 coil

I have these two coils and was wondering will it hurt anything on my new electronic ignition system I installed ? My coil works fine and was for the old point's system. As a back up or run ?
I am also running the old spark plug cables, Is there any reason why I should go to a different electronic wire set ? I have already changed my voltage regulator, Its just looks like the old style.
And should I change to a different plug ?

Thank you for all your time and knowledge .
I have new set of old plug cables on her now and a set of tub seal "Not on yet". That is an old picture when I did the new dist.
