I guess the issue with many of these engines was that lead helped to lubricate and cushion certain parts by forming a protective layer. It was just something that engine makers took advantage of. However, the primary reason for lead was that a small amount was a highly effective octane rating booster. If the parts weren't designed around this, they would still work fine with unleaded with an adequate octane rating.
