Butler Cobra. Spark plug boots melting

Nice job! I love the rollbar grommets. Would you be interested in making another set?

I looked at my car and my wires are run underneath the headers and come up behind the engine to the distributor. Nothing comes close to the exhaust at all and no wires are laying on the valve covers.

Thanks for your appreciation on the rollbar bezels. Making these were far more time-consuming than anyone would ever expect, especially the oval one. And it may not be evident, but one of the other ones is also slightly oval. Sorry to say, I just don't have the time or the inclination to repeat this process to make another set.

Are your headers Butler original? Is your engine a Chevy?

I would have the same header to boot clearance if I were to run the wires underneath. Finding a shorter spark plug will certainly help me. I'm not giving up on this option as of yet.

I must have different headers as my car is an Arntz. I have at least 1.5 - 2" clearance between the wire and the header with a Chevy 350, angle plug heads, 90 degree boot running underneath. I will grab a picture later. I will check the plug type also as the boot covers the whole ceramic portion of the plug. My heads may be newer than yours as I believe they are from a 1984 1 ton truck.

Angled plugs would make a difference for sure.

Knowing what plugs you're using may also be worth knowing.

I'm still trying to determine what the engineering criteria is on a spark plug hole to enable the use of a tapered seat plug. I've read that some heads in the era of mine were designed for both types of plugs.

Looking at the spark plug hole on my heads makes me believe that angled seat plugs may work. The chamfer around the plug hole seems like a perfect mating surface. See photo of my spark plug hole in the link below.
