I have a set of hooker headers on a 350ci motor with Holly aluminum heads. My problem is on #6 spark plug wire touches the header and melts...
This is on the end of wire boot. Have only aprox.
1/4" from spark plug tip to header.
What can I do to fix other than tossing out the headers for another set? Does anyone else have a similer set up? what do you you use.

NGK and Accell are two of the plug companys that make short plugs. I use NGK's and am very happy...

I have the same problem. So far I have had good luck running a fiberglass boot from Taylor. They slip over the 90* boot and can withstand 1200*. Summit sells them under the P/N TAY-2524.

When I bought the car the previous owner had installed one on each wire but I found only #6 is real trouble. I can send you one of the 7 I have left if you want to give it a try.

On my 68' I have the same problem with the #6 wire. I used a wire boot to protect from the heat , it works great.

Hey Funk and Kool,

Do those insulators work well enough to actually touch the header and not melt? I've got a wire or two that are close enough that the boot touches the header if I use non-shorty plugs.

Yup,the sleeves acutally rest against the headers. My headers are uncoated, unless you call rust a coating, so they get really hot.

I don't know if it's boot design but on my closest plug the clearence is about 5/16" - to 3/8" at most with NGK plugs. I run 8mm petronics black plug wires with 90deg boots on the plug ends that on the close plugs are within 1/8" of my headers and I have no melting problems...

Boot design is certainly a factor on mine. The magnecor boots are small and provide the clearance I need. Were I to use MSD, for example, I'd have some resting on a pipe.
