Only cheap HEI works

Thanks for the help! I'm gonna have to follow this up either mid next week, or in early December. I can't order in a voltage reg before I have to drive the car across the state, so since the car has been driving good on the hei, I'm going with the don't fix it if it aint broke method, just wanna get it 300 miles. Voltage regulator is definitely on the high priority list for Christmas break, though.
