Nope you need a MSD unit with, anything from a 6AL to a 7AL3 box. More fire power and less HP drain than a Mag.

I run a 7AL2 with a pro power coil on a 15:1 alky injected 434. On a couple of occasions it has fired a 15% tip of the can without issues.

NGK 8's set @ .024 gap, with a 6AL, same setting with 7AL2. I've never ran a 7AL3, so i don't know the difference.

AR3910s gapped at 30, Extended tip plugs, A lot of engines miss without them.
