Headers and burnt plug wires

[Speedster 229]

I'm running a small block w/ Vortec heads and a HEI ignition.Have a set of coated Hooker comp headers. The 3rd plug wire back on the drivers side is a B----. All others run great with a 90 degree boot up to a wire loom running on top of the valve cover. The only way I can route the problem plug is straight out and over the header to the loom with a heat sheild sock in it. I'd like to run a good set of wires and was wondering if anyone knows of a set that come with more than one boot style so I could build 7 w/ 90 degree boots and one with the straight boot. Anyone else have this problem?? Heating or bending the header is out because they are coated.
