I have read several different articles that insisted that cars with original
never rebuilt heads which ran with leaded gas already have reaped the
benefits of lead and will be fine using unleaded gas for the feasible
remaining life of the head. However, once you rebuild, you should go the
unleaded-head route or use an additive.
