If you mean a Ford V8 from the '30s (hell, even up to the '70s), then no. Seal technology was not very good back then, neither was piston ring tech. Cars were expected to burn oil, and leak oil. Think about all the old timey movies, where a car pulls into a filling station, and the attendant comes out. They would open the hood and check the oil, and sell you some if you were low. It was such a normal fact of life that life worked around it. Imagine in the future when all the cars are electric (or something else?), people will look back on the past, and think - wow people had to stop at a place... for gas?

Well, maybe I was exaggerating a bit with cylinder honing. Maybe. I mean, I wouldn't be surprised. Piston rings were pretty basic back then. But valve jobs were very common. Carbon deposits, I think, were not a big problem. Valves would actually burn up, or more likely the valve seat. A large part of the reason for leaded gas was that it lowered the temperature of combustion (and reduced detonation which caused knock), and that reduced the damage it caused to valves and valve seats. Still, the metallurgy back then was not great, and valves required maintenance. Nowadays, without leaded gas, the metals had to be improved to handle higher temperatures - and they do it very well.

Actually, just about the only thing to do to convert a leaded gas car to unleaded is to replace the valve seats. For a flathead engine, it would likely mean taking the engine out of the car and to a machine shop. Not sure.

Well, a car that old is usually not driven much. But then... there are still people who drive a Ford Model A every day. There's an engine machine shop near me that ONLY does Model A's. Just imagine for a minute. There's a shop that makes a profitable business by working on one type of engine that's from 80-90 years ago.
