I've got to agree with the slightly larger gap idea, worked great on my rich running carbureted Mustang went from 32 to 45 thousands gap, and on my little FI 2.3 Ranger also, spark intensity builds until it jumps the gap, duration of spark can be improved with one of the Crane or other MSD ignitions on a distributor type car, from my experience multiple strike work amazingly well, dont know how a newer single coil per plug setup would benefit but sparks are getting stronger all the time as in newer car s where they have a coil right at the plug itself, Ford made a 2.3 and 2.5 Ranger engine that had two plugs per cylinder, and much more power than the older types, i owned both and big difference, so I would gap them wider and try them, you only lose if they wear to be too much gap. the real proof is all the new cars have a wider gap than the e60's cars before electronic spark.
