It doesn't miss a lick all the way to the top with NGK R5671A8 plugs and I'm running about 16 degrees timing advance at 1.0 bar boost....advanced 12* at idle for low/mid grunt and shaved off as boost builds. Not near as sophisticated as EFI I admit, but the net results are good. Outside of recurving the distributor and going with a digital WUR, it's about as good as we can get with add-ons.

Oops...sorry, off the plug topic! Dual plugs and EFI; well, that's a pipe dream for me. Did I say I like the NGK's?
Depending on the model, I would bet your MSD is CDI. When you mention a gap of .040, it must be.

A well tuned CIS motor rocks....
