Leaded fuel

Does a Jubliee need to run leaded fuel or does it have hardened valve seats in it.

Leaded fuel has been gone for years...decades... and my Jubilee has done just fine. While it is -possible- that the valve seats
could recede, you have to remember that these are low compression, low rpm engines. Run it, and eventually, when it's being
rebuilt, put hardened seats in if needed.

Are you sure that they didn't have hardened valve seats from the very beginning?
