I'm using the NGK V-Power Racing Plugs gapped to .035. Part numbers 6564 (R5672A-8) and it's one heat range colder then stock. So far, it's been running very well and in perfect operating condition. When I installed my Vortech SC and had stock heat range Denso Iridium plugs in there, boy they were running HOT! and misfiring at high RPMs even gapped at .035.
