I would start by checking to make sure all your grounds are clean and in place. Check the ground cable that attaches to the back of the head to the chassis. CLEAN CLEAN CLEAN all ground points. A bad ground can cause all sorts of funky issues.
Also how are you sure its arcing?

is the ECU (computer) grounded in the kick panel?
Is the ECU harness ground near the 10 pin connectors grounded?
How about all of the harness grounds by the coil?

There is a ground wire to the body and I beleive these is a ground wire to one of the heads. Check both to make sure they are connected tight and the contacts and surface are really clean. Consider replacing them if they look fucked up in any way.
Next check your TFI harness to make sure you don't have any bare wires shorting out.
