How about Hedmans shorties for S-Truck V-8 conversions. They exit fairly high and to the rear. I have used them on other swaps besides the original intented use.

When i was younger I used to make headers all the time. Then I bought a big truckload of "seconds" and just plain DNF headers from a famous header manufacturer. It sure made things a lot easier. By modifying a couple of tubes. Instead of making up everything from the flanges to the collectors.
