Is this worth it? 1974 440

Since my 383 needs a lot of work I have a lead on a 1974 440 out of a running motorhome.

From what I can tell this is a fairly detuned motor. and has less torque and horse powere than my 1968 2BBL 383

Are these newer 440 motors Junk???

Or would this motor do ok with my 906 heads on it??

Any advice would be great
