Leaded fuel won't hurt anything as long as you avoid drinking or bathing in it. As for benefits, I don't think you'd see any unless you habitually drive your car very hard.
There are lead substitute products sold that purport to protect valves from damage related to non-leaded fuel.

Marvel Mystery oil is much more economical than AV gas and probably of more benefit when used as a fuel additive per directions. It can provide some valve stem and upper cylinder lubrication and might help prevent "valve recession" in an engine that is run hard. AV gas is high quality and ethanol-free. AV gas might resist hot weather vapor lock better than today's pump gas. High octane fuel is not needed in flathead Packards. 87 is plenty unless you are pulling a trailer across Death Valley.
