RE: IML: Lead Additive

["Ernie Stepney" <estepney@xxxxxxxxx>]

Flathead sixes from at least 1938, exhaust only, maybe earlier. 300D
392's had hardened exhaust replaceable seats as well.

Regarding this subject.
   Does any one recall when Chrysler started to put the hardened
valce seats in the engines.  I remember something about they
started gradually putting in the hardened seats PRIOR to 1975 in
differnet model lines.
