440 Headers for 69 Dart/What are these?

Look closely on both sides of the flanges to see if there is possibly an alpha/numeric part number stamped into them. Lot of guys here can tell you what they are just by seeing a part number.


OK. I triple checked, not stamps on the flanges anywhere. So.....do you believe these are TTI Headers? I just want to sell them for a fair price without Sc#$wing anybody. Your thoughts?
