Performance difference b/t Accel normal and shorty plugs
Any?
World recommended 276 plugs for their heads. I had an extra set of 276S plugs (long story), and they give nice clearance to the headers.
Anyone used both in the same engine with no other changes to get a comparison?

Other than header clearance, there should be no difference between short or full length Accel Plugs of the same heat range.
