SB TTI's, Dougs- Question

Before I mount my adjustable proportioning valve, I want to make sure it won't interfere with the TTI's or Dougs I plan to install in the future. I plan on mounting it about 6-8" down from the original prop. valve on my 68 Dart.

Will there be any interferance with either one of these headers? Can you guys with tti's or dougs post a pic of the underside of driver's side just so I can get an idea of how they're run???

Thanks!
