I confirmed when the heads are off that the plugs fit perfect. The electrode just barely stuck out into the chamber. These are actually what Eden rock recommends.

Pistonbroke, it’ll take way more than that to offend me! I have checked tightness of clamps and such. When I first started the motor, some of the studs weeped. When that happened it “stained” the new heads. Once I was pretty sure they stopped weeping, I cleaned the heads and so far, there are no signs of the same stains I had when I knew they were leaking a touch.
