Using leaded fuel is actually bad for an engine. I have run my antique car for years on unleaded with no problems. Back in the old days, when most gasoline was leaded, I was doing a fair amount of heavy engine work. One of the things I noted was that the exhaust valves in particular were prone to burning. They were usually also caked up with lead deposits. This was back in the late 1960s into the early 1970s. Some years later, after unleaded fuels became the normal fuels, there was a notable change in the inside of engines. One thing that I noted was that burned valves and valve jobs became much less common. I also noted that the inside of engines was a lot cleaner. There were no longer pockets of accumulated lead residues found throughout the engine. My opinion is that removal of lead from our fuels was a good thing. The only possible thing that you may need to do in the future would be to install harder exhaust valves.
