Headers or Manifolds for a 67 4spd Cuda

Well guys I called TTI today and had a good heart to heart. I was told by Mr. Raby that if I use a TTI Z-bar along with a set of the 1 3/4 or 2" headers that I can use them.

Will anyone who has used this setup please chime in to let me know how it worked? Thank you to everyone who has already chimed in. Including Mr. Denny:)
