Sounds alot like spark plugs have too much resistance. Maybe wrong plug or too wide of gap. Most of the time if you see an arc between the dist. cap and ground or the coil tower and one of the primary terminals it is bad plug wires and or spark plugs. But to arc from the plug wire across the spark plug insolator is rare. What number plugs did you install?

Arcs between the plug hexes and the head suggest that the plugs are not grounded to the heads thru the threads for some reason.
Did you use some type of anti-seize?
I would measure resistance between the plug hex and the head for confirmation.
Coil sounds fine.

Rereading your post, I see you said it is arcing between the plug base and the cyl. head, not across the plug insolator. I would check to see if the ground strap from the engine to the body is in place, also check the coil braket grounding to the body. The coil is grounded to the body not the engine. There needs to be a ground path between the coil braket and the engine or the spark will try to find a path, like through the air. Think radio.

I think you will find the black with red has power w/the ignition is in the start position.
It bypasses the ballast resistor for starting.
Put an ohmmeter between the hex and the head yet?

One observation; not related to your issues - Are you missing a radiator ground. This is one that connects the radiator to the right upper fan shroud bolt??
