You have to be INSANE to have long-tube headers on a big-block A-body Mopar!

actually, the spark plug wires were routed the way they are by the previous owner. you can install plug wires in a better manner than what you see in the picture even with headers. but as you note, you have to be careful to keep plug wires away from the header tubes which get extremely hot - like red hot hot. it is a much better idea to wrap header tubes with heat wrap which i intend to do once i get to that step which at this point, is pretty FAR off!

I don't know man. I'm not an advocate for header wrap at all. They hold moisture and as a result, rust headers out pretty quickly. Also, they can do the exact opposite of what they were intended to do, especially in close quarters. I've seen wrap actually contribute to overheating, because they hold the heat in, instead of allowing it to dissipate. I know on my stuff, I'll never use it.
