If you have a set of calipers, carefully measure the depth of the cap from the bottom to the tip of the carbon button. Then measure from the surface the cap rest on to the spring contact that rubs on the button, is it actually making contact or is there a distance that is causing arcing and overheating of the carbon button. It must actually rub on the button. I was surprised to find unusual internal dimensions in MSD's Small diameter Pro Billet Distributor and their "Red" cap. I measured over .160" from the upper surface on the tip of the rotor to the bottom of the outer tower contacts, that seemed excessive.
