When I last ran Top Fuel back in 97 or so, we were using two mags...Supermag V's. We were making approx. 3500 horsepower spinning 8000 in the lights and never had any ignition issues what-so-ever.
So, what is on top of a Supermag V triggering the spark? Right, a single set of points!
Points or HEI do not generate the spark, they only trigger when it happens.
30 years ago when I was street racing this stuff...High Compression BB's and Hemi's, I tried every ignition system under the sun. I ultimately found that a good quality Dual Point distributor gave the most reliable performance with the least amount of complication. If the point ignition is set up correctly, there is zero performance advantage when changing to electronic.
