Actually since cats were put on cars after 1975 and all vehicles after then were required to use unleaded gas it would be 1975. But Cats were first used in 1973 on some cars.
And since D3VE heads were used clear into the 80s many many of them DID have hardened exhaust seats. But the point is still the same, do a valve job and you take out the induction hardened seat and need to replace it.

And I did do a search, couldn't find the info.
