They use the long reach plugs and I assume that the same ones for Eddy heads could be used. I have a set of FR4 NGK's in the tool box but they might be a little hot for a 10.4 to 1 engine. What would you guys use? Don.

I use a 7 or 8 in my 12.11 e-headed 470. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....
