The date code is below the passenger side head and should look like 23F8 which is 23rd of June 1976. Unless its a replacement engine (Nasco) the date code should be on or before the build month.
The month codes go A=Jan B=Feb etc and "I" is skipped. The last number is the year code but needs to be checked against the engine number prefix and block features.
