What kind of plug wires are you guys running

Used to run Taylors, still have a few sets "in stock". Firecores would be my 2nd choice. MSD would be 3rd.
If you're certain it's an ignition related miss, ohm out the wires without removing them from the engine so the same bends and pinches are present. The manufacturers can tell you what the resistance should be per foot. Sure it's not a bad plug or pickup?
