[FWDLK] A Question on Hardened Seats

[Jason Rogers <jasonrogers6@xxxxxxxxxxx>]

And not to be confused with tight rumps...

 

The flathead engines had hardened exhaust valve seats, starting in 1933.

 

What about the early V8s and the Slant Sixes, prior to the unleaded fuel era?

 

 

Thanks,

Jason.
