My favorite "problem solver" is the special spark plug originally designed for AMC and Chrysler in the late '70s when they were trying to make engines run reliably with extremely lean and stratified charges. This is Autolite 985 or Champion RN13LYC or NGK ZFR5N
I may have asked this before, but is there a similar super-extended-tip plug that fits B/RB block engines, essentially replacing the Champion RJ12/RJ14 plugs? The only difference between them and the RN series (as far as I know) is the much shorter thread reach needed on the B/RB heads
