School me on 340 exhaust manifolds

i will admit that i will never fully understand the resto crowd,but as i see it,if the manifolds are not the ones that came on the car in the first place they are not the originals anyway and in that case you might aswell get the reproduction ones since you will never find the ones that came on the car anyway.
just my point of view.


that is the correct answer....not originals ones...not number matching...
