Well here goes, my opinions may be worth what you paid for them.
.......
One book that goes into some detail was written by Dr. Christopher Jacobs, who wrote The Doctor's Guide to High Performance Ignition and I guess is still making ignition systems. I thought the company was gone. He writes about things in very attractive engineeringese and I don't know what to believe and what not to believe.

I definitely liked Chris Jacobs book too.
I was especially interested in his comments that “He really likes ‘Booster Gap’ spark plugs”.
I wish I could buy some Irridium tipped Bosster Gap sparkplugs to experiment with.
Barring any of those, my second wish would be for ignition wires with built in booster gaps.
Chris Jacobs statement that daily driver V8s in RVs and pickups benefit from low turns ratio coils that produce long burn time sparks is worth noting too.
