 Not so much a design goal, but since these aluminum head engines have hardened valve seats, lead is not needed for exhaust valve lubrication. Remember, tetraethyl lead was added to gas as a cheap way to boost octane, not as a seat lubricant.

You're saying that to run with unleaded gas was an original design goal?  Is
