Should I buy this 440?

I picked it up today. Here is a pic of the top pad and the 440 with a pile of parts. It has the 452 heads and is not locked up.

Interesting. The two police versions i have are stamped 7T E440HP and 8T E440HP (1977 & 78). Or something like that. Good score anyways whatever it is.
