Mine weren't shorties, but I didn't like how close the #7 tube came to the power brake booster. The plan was to move the #7 & 8 tubes, but I figured while I was at it...
Latoracing built his own stainless headers and has a real nice write-up on them in his build tread.
Doing mine was more time consuming than difficult, and gave me a reason to buy another tig welder.
Before:
After: I also moved the #1 tube a bit as it was too close for my liking to the shock tower.
No reason for the tube to be this close to the valve cover and brake booster.
I didn't care for the shape of the #7 tube at the flange.
So I started fresh and made a round to oval starter tube.
This was my first attempt at header mods and was much easier that I first thought. Bob, I'm confident you've got the know how and skills to get this done.
