Also check the air gap between the tip of the rotor and EACH of the four pins inside the distributor body. Perhaps the gap on #1 and #2 is too great. The gap when using a standard head should be about 0.025, but you may want to experiment by widening that. My head is 6:1 and I find a gap of 0.030 works very well. Some people use an even greater gap.
