I am having trouble getting the spark plug covers to work well with aftermarket wires as well as the stock wires. The '55 331 hemi in my '56 Savoy has original wires in it and the insulators sit relatively deep in the tube. But the back end of the cover crushed the wires, and over time, they began to fail. New insulators (made by Taylor and Mopar Performance) stick up higher - likely because they are made to work with the 426 style tube boots. These seem to stick up too high to work well with the wire covers. They do fit, but push down on the wires and create a really tight bend at the end of the insulator. What are people doing here? Is it possible to re-use the original insulators on new 7mm wires? I haven't had any luck getting the old wires out of them. Has anyone tried cutting the Taylor style insulators shorter so that they fit better?

Also, it seems that if I remove the upward "C" clip at the end of the covers that it would help to give more room for the wires back there. Removing it may make it easier for them to slip under the cover and get crushed, but I am wanting to give them as much room as I can to prevent future failures. Has anyone tried modifying the exit point of the covers to make it work better?

Anyway, just looking for advice to keep them working well with the covers in place.

I cut the end off my wire covers so the bend isn't so sharp. 8MM Accel straight boot wire. 331

Do those use the plastic Taylor style insulators?

8mm wires take up alot of space. That said, there are 2 styles of wire cover...the truck piece extends past the valve cover a bit farther than the other so it might help you if you can find a pair.
The late crop of plastic insulators can be cut down with a fine tooth blade and some folks do not use a hard insulator, just a long boot. I will suggest always using some dielectric grease on the inside of the boot to make removal easier later on.
