What IS important is that the carburetor, mounting gasket, stainless plate (if used) and the intake manifold are ALL from the same year engine!

Plates were not always used; different plates were used. It all depends on everything matching.

Not that mismatched parts will not work; but it adds a degree of difficulty in checking everything to make sure everything seals correctly, including exhaust.
