There is always hotrodlane.cc, they have some shorty headers that may work, but if memory serves, they are a tad pricey. Look them up, see what they have to offer.
That's what I used. I bought them just tacked together in case they needed to be modified. The one thing on my car I actually lucked out on........they fit perfect.
I have heard the Jeep SRT8 headers are much tighter to the block and may fit better than the car version....they are different.
