Here are a few header designs from my "Whatever Floats Your Boat" files:
A Super Stocker using a "180-degree" header design. The theory being that the 180-degree design better suits the firing order for scavenging.
Another 180-degree design. Over the years it has been proven that there was nothing wrong with the "theory", but there was also nothing particularly better about it either.
This is an Olds powered street rod. If the design looks like the old Ford flathead design shown above, it is (several early overhead valve engines like this Oldsmobile utilized simeased exhaust ports, including Cadillac, Packard and others). The fact is that if a car is a street only cruiser, there is nothing wrong with a simple header like this.
There are long tubes, and then there are LONG tubes.
This is a typical Mid Length header on a supercharged Chrysler Hemi Gasser.
