1971 LS-6 Corvette's had the later manifold with the cylinder # on each intake runner. I have never seen a 1970 LS-6, L-78, nor L-89 with the "Numbered" intake on it from the factory. I would assume the over the counter 569 manifolds built after the 1970 model year had them as well., but you know what assume means.
