Thanks, all makes sense. I have a good number of modifications that are aiding and abetting the quantity and quality of the incoming air / fuel charge. Getting a complete, clean burn is worth the occasional set of plug wires plus cap and rotor. I've got an MSD coil and so it ought to be up to the task of the MSD box plus the recommended plug gap. In thinking through all that we've talked about, I can see if the plug only pulled enough juice to jump the gap, that the related components would last longer. But I think when the distributor sends the zap, it's sending the full voltage / amperage of what's available, therefore I don't see that the longevity would be different depending on the gap. Maybe I'm just not getting it and I don't mean to monopolize your thread.
