UPDATE: Well what Kanter sent me (and I installed) was the RH18Y plugs, so I going to presume these are merely resistor plugs and that all will be well.
Next on tap: putting the valve covers back on, then the new wires, finally get into the distributor. Moving along slowly but surely!
RH18Y: R=Resistor, H=7/16" Reach, 18=Heat Range - hottest in the series, Y=Projected Electrode. RH18Y has a longer reach (threaded area) than J18Y which is a ⅜" reach plug. I may have been mistaken about using J18Ys in my 55 Clipper. The parts cross-reference shows H series Champion plugs for the V-8 along with the N series (depending upon which cylinder head - early or late). You don't need or want to use resistor spark plug cables with the resistor plugs. Plugs or wires, but not both.
