I wouldn't worry too much about the EI harness and plugs. Any decent setup should have plenty of power to overcome problems. If I remember, most auto leads werr 500 ohms/foot and the plugs are 5K. Also, you are getting the sizeable RPM drop when you turn off the EI, correct? That points to the Mag.
I would worry about the Mag side. I don't know the spec for the leads, you'll ahve to look that up. You can do all four and any major difference would be a problem. The plugs should be 1K and they often fail and give high resistance. The mags don't pack that much of an electrical punch and high resistance in the plugs will cause a weak spark.
While I don't have an EI installed yet, most seem to report a very small or non-existant drop when the turn off the Mag. This makes sense as the advanced timing of the Mag ends up negating the need for spark from the Mag. The fact that you have a 50 RPM drop makes me think that your mag timing is advanced beyond spec.
