Need a little info: date coding on hemi heads

[odcics2]

Got a buddy trying to put a hemi back to stock, as much a possible.
It had alum. head, rat roaster, headers, etc.
He has access to a few heads but needs to know what numbers he should be looking for to get near a '69 build date.

Any help appreciated.  Thanks.

Anyone?

Just pulled out my Bible, old DC racing manual. It states 68-71 Street Hemi's used part number 2780557.

Original 64 heads are PN 2468014

65 Super Stock heads are aluminum PN 2531108

The DC Bible is not a restorer guild so it does not list date codes.

I wonder why it did not have PN for 66 and 67 heads? 

If you like me to do a little more digging, let me know.

The casting number for all '66-'71 production iron Hemi heads is 2780559. There will be a casting date on each head and, for authenticity, it should precede the scheduled build date of the car by several months.

Thanks - I'll pass the info on.
