I have been reading up on this and since I have been messing with my spark plugs here recently, I have been thinking about doing it on my next new set. It appears that the "opening" of the plug electrode should be +/-20 degrees or so of facing towards the valves (up). I checked one of my just to see where it was at and it appears that the opening is more like 45 degrees from facing the valves straight up. In the attached photo, the green mark on the plug represents the electrode. 7434507-#7-2012-1.JPG (371 downloads) 1970 YO7 A66 [Canadian Export] F8 Challenger 340 (Currently in shop for stroker assy.)
