New 440 Build - Ignition Question

I am building a 12 to 1 440 and wanted to know what I'll need to spark the fire of this motor...Ignition, octane fuel? etc...

440 .30 over motor w\516 closed chambered heads, pocket ported, gasket matched with 2.14 intake and 1.81 exhaust valves. The heads have been cc'd to 73cc's. The KB pistons I am using say that this combo should yield approx 11.3 to 1 compression ratio using the felpro blue .040 head gasket. I would like to use the steal shim .020 head gasket that should yield approx 12.02 to 1 compression ratio.

Thanks in advance...

I usually just run an MSD dist. No vacume advance, and switch out the springs and just lock it out so there is no advance curve. I would start at 33-35° total advance.
I use the MSD digital 6 box in both my Duster and my DTS dyno at work. Love them.
