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

I had a set of those in the 80's. Never again. Tires rubbed (even small 195/70R14), low ground clearance at the flanges, hot on the feet...
Edited to add: really close to the master cylinder. I tried it on a 440 and had to make a relocating plate. Body clearance even worse with the RB.

I have mine sitting a little higher than stock height so I don’t have the ground clearance to flange issue or tire rubbing. I used a DEI starter heat shield under the master to protect from heat. I’ve got about 4 years/20,000 miles on this set-up so far & it’s worked well for my application.
