So should I add lead to the gas?

And why?

Or does it run fine with unleaded?

All the Studebakers I've known, from 31 to 66, have had no problems with unleaded gas.:)

You should be fine with unleaded in your car.
The tetraethyl lead is used to lubricate the valve seats to prevent valve recession. Newer engines that are designed for unleaded gasoline have hardened seats to take the lack of tetraethyl lead into account. Studebaker valve seats were of prettty high density, so unless you are towing, or lugging the engine under a high load for long periods of time,you will probably take decades to get enough wear to warrant replacing the valve seats (considering our limited use). Put unleaded gas into it and drive!
One thing to consider, is adding a quart of diesel fuel per tankful of gasoline. The added cetane will help prevent spark knock, and the top lube will help to prevent vapor lock on hot days. I bought a gallon gas can and fill it with diesel. Saved my oil change quart bottles, and re-filled them with diesel. Keep one or two in the trunk for trips.
Works great!

You should have zero problems with your '49 on todays pump gas....if you had an R-1 in a late model Stude..then I'd say you would need all the help you could get.

BTW, Ethyl Corporation approves of only one leaded concentrate that is not "snake oil" and actually does what it claims..Torco Race Fuels..specificly the leaded "Accelerator" sold in qts, and five gallon pails.

The metal in the V-8 head seat area must be above average. Had a head valve job done recently. Watched the machinist cut the seat and he was very impressed at the hardness of the seat area. It did not cut like any soft stuff iron.

The "diesel in fuel" issue was discussed in a previous thread (dealing with fuel boiling or vapour lock, as I recall). One member provided a very good explanation about why modern fuels have lower boiling points as they have "single chain hydrocarbons".
Anyhow, the upshot was that by adding a bit of diesel which contains "multi-linked hydrocarbons chains" you'd raise the fuel boiling point.
That's what I can recall, at any rate.
