Brake line routing question
hello everyone I have a 1977 Ford F250 351M c6 trans 2wd I have a pair of headers on this truck as seen in the picture I have not started up or driven this truck yet since re-hauling the whole truck my question is will my brake lines and proportioning valve be ok like this with the headers that close?

I agree that’s what I was afraid of there routed as factory right now so I had a feeling I would have to change it I’ve had to change everything else 😂 thank you for the help!

do you know what type of brake line would be worth buying to make custom ones?

At the very least, I'd fashion some heat shielding that sits out from the brake lines and header pipes so there's an air space between each, so heat is not transferred. You could use tin or copper sheet or aluminum. Factories use thin aluminum with a fiberglass mat like layer bonded to it to shield parts from exhaust. Hard to burn fiberglass.

I'd recommend shielding the proportioning valve with header wrap and I'd make some sort of alum cover as well to deflect even more heat. I think between those 2 things you would be okay. Well, and I would redo the soft lines with hard lines at least further down the frame rail away from the header.

I do have a question I was trying to find another set of headers to possibly use but would I still be in this situation with any set of headers?

Ni-Cu ...nickle copper is a good line to use. Don't forget , double flared.
I would say try a heat shield but, it looks like it would be a bit close

I remember reading that 3" should be maintained between exhaust and brake lines. Cannot remember if this is from Hot Rod magazine, or Classic Trucks etc. but I have always followed that. Granted, just because it showed up in print does not make it right. The concern is that you will get a "spongy pedal", or as tbear853 points out you can even have brake fluid boil.
