LA head casting ID help.

If it is a 72 or 73 engine I would say that those are probably the original heads.

Hello jadaharabi,
Date code on block is also 72 But its in a 73 H code duster Not numbers matching so i am guessing that the OEM motor was pulled and this is the replacement. The Intake is date code 73.
Happy Mopar :)
Thanks in advance
