Well I'm not 100% sure about this, but I think you need to run two 6 volt
3 ohm coils in series because points like 5 ohm coils. Two 6 volt coils in series would be like a 12 voilt coil, Two 3 ohm coils in series would be 6 ohms. Does this sound right to you all? Lower than 5 ohms burns up the pionts.

I am sure about this, you want to run the timing at about 5 to 7 degrees less total advance. Two plugs give a faster better burn. Put the timing mark to the very front of the timing plug hole.

Plugs, you did not say if you have short or long reach plugs. I run Autolite 4265's on the long side (left) and 4275's on the short side (right).

When I dual-plugged my Sportster, I had to run a longer reach plug on the right side do to the thicker boss. I can't remember what coils I used, but I think I bought a kit from J&P Cycle. The price was right and it saved me a lot of time setting it up. The timing should be left alone. More efficient burning doesn't make a difference in when the spark plugs should fire.
