Sorry, no pix, but the following may be clear enough....
I had Hedmans on a 360 in a Dart Sport. They had #3 tube running near the valve cover, right over #5 and 7. I used 90 degree boots on 5 and 7 and ran the wires DOWN, then sweeping around and back up to the distributor. The other cylinders were fine to use the straight boots.
