Uncoated Headers Burning Plug Wires. Solution?

Uncoated Headers Burning Plug Wires. Solution? I just completed my LS6 longblock install this past week and I went with a set of uncoated Hooker shorty headers. I had VERY bad luck with a set of LT’s, so that’s why I went with shorties. I know I should’ve gotten them coated, but I’m just trying to solve the problem for now.
If you have uncoated Hooker shorties, are you burning plug wires? When we did the initial “run-in” (2500 RPM for 20 mins) on the new LS6, the headers turned a nice orange glow from the heat and actually melted my new $70 Taylor Thundervolt 50 wires
I just ordered another set of Taylors and I also bought 6” sleeves that are supposed to protect the wires up to 1200 degrees. Should that solve the problem? The wires aren’t actually touching the header, but there’s as little as a ½” of clearance in some spots.
Do headers normally get that hot, or was it just because we were doing the “run-in”? Will the new sleeves solve the problem or just prolong it happening again?

You can get a fiberglass sleeving for plug wires.
That might suffice for the immediate problem.
Another option is to rig some sort of loom or
clippage that keeps the wires from contact.
You aren't supposed to wrap the headers all
the way up to the heads (where the wires
are) as I understand it, they can't take that
kind of heat - like, you wanna go from orange
(that you can see) to yellow (covered up)?

Actually an orange glowing header means unburnt fuel is getting burnt in the header tube, at least that's what I remember from somewhere...I used to have an old 340 Mopar 71 'Cuda that would do that. It had a big ole lumpy "purple shaft" cam...spec out at like .502 lift and 292 advertised dur. I can't remember the LSA probably 108 or so. Very lumpy.
The headers would glow orange while idling. Yours may not be the same problem.
