906 or 452 which is best overall

I have been cleaning out my garage and storage sheds and pitching just about everything but mopar parts. I came across a complete 69 383 out of a roadrunner and a complete 74 440 out of a ????. The 383 looks like it had a million miles on it. But the 440 looks like it was just rebuilt. Bearings look new, cross hatch in cylinders look fresh, top of pistons were clean.
In another shed I found 2 sets of heads complete, one set are 906's and the other are 452's.

Now for my question, which are the better heads stone stock and which are the better heads ported? Also which heads came off which motor? I know there are a lot of variables but just a general opinion is what I am looking for.
