Do they make a under chassis header for a A-Body with a 440???? Or would you just build/buy a 400 B motor for more clearance??
The 440 chassis headers like the older Pro Parts don't fit worth a hoot on a low deck with stock mounts  I bought a set of the older Pro Parts from Bill before Mazolini bought the Name, inventory and rights to have new ones made, mine don't fit worth a hoot on my 1969 Dart GTS with the original 383 K member and mounts  I bought a set of the 383 headers from a member and sent the left side back to Mad Dog to have him fix what the other guy bent up I was going to swap them but I have since bought a stock set of 383 exhaut manifolds for my car  I'm going to keep one set of the headers for making dyno headers with EGT fittings but the other set may be availble, let me see and if so I'll post about that on here
