Leaded vs unleaded gas

Does anyone out there know if the 1970 1.9 GT engine had hardened valve seats?? I understand that they are needed to prevent valve "beat in" which results when using unleaded gas in an engine originally designed for leaded gas. Thanks.

Thanks guys for your opinions. I think I will take your advice and run the engine until it needs a valve job. It has 70,000 miles on it so it should go another 30,000 without any trouble.
