Simple question. 1973 914 2.0 Runs great!. I'm not the original owner, but he says he's always used unleaded and owned the car for over 25 years. I have no idea if the heads have been off & reworked but it seems in 1973 they would have used leaded fuel in this car. And I hear unleaded is hard on valves unless they've been replaced with hardened valves & seats. What's the skinny? Do I need to use an additive or is unleaded premium ok to use?

Engines with hardened (i.e., steel) valve seats don't need lead. Cast Iron heads with the seats cut right into the head do. Porsche used sodium filled valves in many applications for YEARS before anyone ever thought to remove the lead additives from gasoline.
