I just took off a set of headers from a 68 Dart with a 360 in it. They are the Flow Tech headers #33100FLT, ceramic coated, and worked very well on the car and are in excellent shape. They never saw the street as the car is a track only car. Let me know if you're interested and I can get you some pictures.
I have a Weiand Stealth # 8022 dual plane. Clean, no stripped threads and painted black on top. $150 + shipping from 32117. I'd have to weigh it to get an exact shipping price, but it shouldn't be over $25.00.
I can get a pic to you after I use up a roll of 35mm film.
