big block burning plug wires

did a quick search and came up with nothing so I figured I'd post something here...how can I stop my TTI headers from burning plug wires??? I am pulling my hair out trying to keep those @#$% headers from burning 2-3 plug wires...tried searching around for the smallest diameter plug wire, tried finding the shortest length plug, used fire retardant plug boots...all failed...I have a 440 in a 69 Dart with the big TTI headers which I had ceramic coated...anybody???
