Exhaust Manifold Casting # ? - 05/08/13 07:19 PM

I have what I think is a 70-71 hemi driver side manifold part number 3418453 and there is also another number 5071 on it. Is that a date code meaning something like the 50th day of 1971? Or what is this number and what would a date code look like for this part?

Maybe it's 5-07-1 / May 7, 1971

If it were 50th day of 71 it would read 0501
