Yup..I index the ground electrode towards the intake as I use the older, higher comp head. I side gap the plugs at .030. The half ground electrode as I understand is to help keep carbon chunks from getting caught in between during the days of 40wt auto oil. Since point to point is ideal for easy spark I side gap and point the ground electrode. The older head showers the plug with intake juice so I use a b6 on top and a b5 on the bottom. ngk of course..
