Re: '41 120 Sparkplug gap question

I didn't think so but was just wondering if there could be differences in copper ring gasket thickness or tolerances between plug mfgs.

To have them all squeeze a more or less equal amount would make me suspect something in the head or head gasket thickness, ring gasket, or plug was different. I'd have to go back and read what happened or was done when the car was laid up and stranded in the driveway but do remember the mention of recent exhaust manifold work. Don't recall a mention of head work so if nothing was done there I was thinking plug related as the denominator.
