World Heads Sparkplug?
08/18/09 at 4:46pm

I have a 358 Chevy,using a Holley750cfm, on Gas. Running WorldProducts Heads, takes a 5/8 SparkPlug. Have been using Autolite#AR134 plugs, gapped @ .045 ,with MSD distributer. About every 4th race, the plugs seem to loose fire at Lower RPMs. They aren't Fouling Out,just run like crap. New set of plugs,& all is well.
The #AR134 are a short reach plug,am I gapping them to far, our is there a different plug someone can recomend? Thanks
