I just bought a '50 pan and it just occurred to me that gas was leaded in those days. How do these motors run on the present day unleaded gas? Any problems?

Octain is more than enough but if I remember correctly they used bronze intake seats for the valves. Not sure how hard the exhaust seats are but I would think you would get a lot of wear in the bronze seats without lead. Marvel Mystery Oil mixed in the gas might do the trick in this department, but some research is needed to be sure. This product really does work well with many problems.

Had that issue a few years back, found an additive that added the led to the gas. May want to check your local auto parts stores.
