Tried a version of this in general but nobody chimed in.
Back in the day Hemi engines had an "upgrade" that would essentially link both plugs on each cylinder together and fire them at the same time instead of the waste spark that I guess was only to clean up emissions.

How do the plugs fire on a 6.2? Still a waste spark ignition or do they fire at the same time?
