The relation of the "dot" cast on the manifold is an easy ID spotter to tell if its intended for a low-deck or raised deck application. The "dots" are roughly in the same location relitive to the cylinder head flange. You can see the 440 one is longer after the "dot" to reach around the steering...

You have a 383 manifold on a 440. The position of the outlets are at different hights.

IIRC the '66-'71 ('72-'73?) 440s all had the same compression ratios between the low performance & high performance variants of a particular year. Only the '70-'71 440-6bbl engines received significantly higher compression ratios compared to the 350hp/375hp engines. Most of the power...
