Yes, HEI's love to arc inside, that's why they made the cap soo big!! Often, they burn through the bottom of the rotor, and toast the module or the mech. advance. Electricity will always take the path of least resistance, which should be to the plugs. Could be bad wires, or bad plugs, or too much plug gap. gap em at .040, and I like spiral wound wires, good radio supression without high resistance. If there's any carbon inside the cap or on the rotor, replace em, even if they're brand new. Don't forget to change the little carbon button that brings power from the coil to the rotor.
