1965-70 Impala headers? What’s everyone using these days for long tube headers in the 65-70 Impalas? I did a lot of reading, and the preferred headers seam to be the Dynatech LS swap headers for a 67-69 camaro. Part #715-21410. Unfortunately those are out of stock everywhere and they may be out of production. They are unique because the number 3 header tube runs straight back and turns down behind the number 7 tube. That really helps with steering box clearance.
I'm using Speed Engineering 1 3/4" longtubes for 64-77 A-Body. I did need to dimple the #3 for steering box clearance but that was straight forward with my press and a socket.
I'm also using an Autogear 4 speed and mechanical linkage. I tried their 1st gen camaro longtubes but they tucked in more and hit my Quicktime bellhousing flange.

I also used Kwhizz's adapter plates. The downleg on the engine side of the zbar is very close to the header pipe but clears just enough. I played around a bit when I did the install because my car didn't have the zbar bracket on the frame originally.
