Spark plug gap .035", the compression is 15%, limit is 10% out not by much I'd run it and recheck later in season. A coil that has a primary resistance of 1.2 ohm or less does not need a ballast resistor. Msd blaster coil 2 is .7 ohm primary resistance, so it should be good to go. That spec was giving to me by msd tech support.
