what heat range plugs for msd box+wires?
I'm installing a msd 6a box and 8mm wires tomorrow on my 87 iroc 305tpi. I know I have to change the plug gap to about .050, but should I change the heat range also? I don't really have any mods. Any suggestions? I have regular delco 43s in there now. Thanks!
