Technically, yeah, they're manifolds... but everybody
makes the distinction of factory headers because they

These 67+ manifolds, when installed on the assembly

(3 bolt flanges vs 2), brake line to right front wheel, and
last but not least, wiring.

Look at the link in my previous post, it was meant to
steer you in the right direction. It just happens to be
the guide tube that goes on the motor mount.
