Your mechanic says that or the header folks say that? And where did you get the headers btw?
Maybe you could get a high temp hose/hose cover, split it open and wrap the hose in question in that so that it won't bump into the hot header? :shrug: Just an idea you may try.
I don't see what Marty can/should do. The headers are the same as they've been for who knows how long. If it hasn't been damaged in shipping, (which it probably hasn't), and if you dont like how the lines run close to the pipes, then find a way to reroute it. extend the rubber part, or make a metal part to pass by. I'm sure with a little bit of finess(sp?) everything will be fine.
Yep, that is the exact plan - we've no idea what to use though.
