hatch,
I've never been a big fan of shorty headers! Because no matter how good they are designed to scavenge, there is still a natural restriction that you can't do anything about at the header flanges where they connect to the H-pipe. If you hold up any shorty header side by side to the stock headers, you will see what I mean. The size of the hole at the flange of the aftermarket shorties is basically the same size as the stock headers. So what are you really accomplishing with shorties? Not much!
On the other hand, with full length headers there is no restriction where they meet the H-pipe. There is usually a 3" collector that connects the four header pipes to the H-pipe.
Full length headers make more power and make a small block sound bigger than it is, even with quite mufflers. The only disadvantage is that it takes some custom work to make them fit.
Shorties are a good choice for people who live out in the boonies and don’t have an exhaust shop nearby. They can install them in their driveway with relative ease. But if you have access to an exhaust shop that can do some minor custom work, long tube headers are the only way to go for sound and power!
