My caps are original '86 equipment with a built-in ceramic resistor. My top end however, is off an '89 which requires JR9C spark plugs, which are resistor-type. So basically Im running a dual resistor setup on my ignition. If I were to replace those ceramic rods in the caps with copper ones or another metal with high conductivity, I'd imagine it would be very beneficial on my setup with high compression running high octane leaded fuel and an ignition advancer. Or will the resistor plugs still nullify the spark to what its currently at? What do y'all think?
