Ford Mustang Removing Headers

Although it might be considered optional, we strongly recommend taking the following steps because it makes installation considerably more straightforward. Jack up the engine, support it with a block of wood under the oil pan, and remove the motor mounts.

With direct access to these bolts, it takes only a few seconds to remove them.
