Some ignition questions

This is the other diagram I saw here on FABO....it's the only one that specified a resistance reading on the ignition coil......so much good info on this site! Does anyone have a HEI setup running a higher resistance coil than the .32 ohm ? I would like to keep the HEI for roadside emergencies if need be but its only useful to me if I get it to work right on my car.Also some info I read in a Flame Thrower HEI brochure stated not to use solid core ignition wires not sure why or how correct that is.....but right now more concerned with getting my car back on the road for some topless driving!!
