The firing order for a Ford flathead is 1-5-4-8-6-3-7-2. If you look a regular flathead manifold over, you will see that one side feeds cylinders 1, 4, 6 and 7, while the other side feeds cylinders 5, 8, 3, and 2. This just makes common sense. If you take into consideration the unique cylinder numbering convention for flathead Fords, you will see that the cylinders fire on alternate sides of the engine and alternate sides of the manifold.

Clever, those Ford engineers.
