That's typical of arcing. The rotor does not actually physically touch the contacts, it just gets extremely close... close enough for the electrical energy to jump the tiny gap as a spark. If the gap is slightly too big, due to manufacturing tolerances and/or (I believe) if the plug wires are defective and shorting out to ground, the spark in that gap starts to burn the contacts.
Given the plug wires are all-new, possibly the problem will not occur. But you should keep an eye on it.
BTW... did you use carbon-core or solid-core plug wires? The solid-core wires are better for a points-type ignition, but may cause some radio interference.
