Ed, I am sure the list will correct me but I seem to recall a thread on this topc a few years ago and the concensus was that Chrysler had been using hardened valve seats since the early 50's. More of a chevy and ford problem.

Supposedly the lead in the old fuel acted as a lubricant and coolant to prevent the exhaust valves from 'eating' the seat area. I will probably do this,,,but,,,,has anyone ever used the lead substitutes presently on the market instead of installing the hardened seats?? Has it been successful at all over the long haul?? How 'far' will one be able to go without installing the seats??
