I grabbed some RV15YC4 Champions for my (sometimes painfully) stock 351c/'73 Pantera L (dual points/external res.)
I'm also replacing the coil while I'm in there, and checking for a good signal from that resistor.
They all came out of the box with a gap of .046, and is that the recommended gap for these plugs?

Sorry if I'm among the wrong DT models forum, but it's because I was drawn like a moth to George's spark plug chart!)
TIA..........
