try-y headers on a 67 GT350

[shelbydoug]

One more question, anybody having any problems with the plug leads and melting with heat from the headers , I,d really like to keep the stock black of possible  , nothing looks worse than bright yellow or blue when you open the hood.
            many thanks

Cannibalize a set of silicone wires and swap the boots.

I have a big block a small block and an aluminum head Cleveland. In my view the issue is the boot melting against a hot header. The silicone boots will melt in the spot where they touch but that kind of molds them to the location.

The Marti boots are the original Ford boots and eventually will dry out and split from the heat exposure. It doesn't happen overnight though. Some last a lot longer then others.

In all cases you don't really see the boots on my cars. The BB the wires just disappear below the valve covers entirely.


I bought too sets of "Ford Racing" grey 9mm wires. I put a set on the Pantera. In 15 minutes both the boots and wires spit.
