I wonder if a lot of the increase in torque people notice with the twin spark is to do with the EFI.

When I converted my 2.0L Nord engine from dells to EFI that was one thing I noticed along with very smooth running.

Hills that I use to have to slip into to fourth just to maintain speed I could now accelerate up in fifth. It also pulls smoothly from under 1500rpm in fourth and feels more like a smooth 6 than raucous 4.

I was going to swap to a twin spark but am wondering if after all the time and expense I would notice much of a difference.

BTW my Nord does have a ported and shaved head but that along with 105 cams is about all that has been modified internally.
