Header clearance

I have a power booster on my 65 Dart w/ V-8. My booster just barely clears the Weind valve cover, but that should be higher than the #6 pipe shown. I expect the problem is that the #6 pipe might hit the stand-off bracket, since it runs close to the firewall. If so, perhaps you could file the bracket to clear. However, if it gets into the lever assembly, that wouldn't work. Try to compare your firewall to the photo to judge. BTW, what are the 2 hose clamps doing on that #6 pipe? Looks strange.
