It's a toss up -- I've read pros/cons. If you will be running the livin' hell out of the motor for extended period of times -- hardened seats are a must. But if you're just cruzin' with occasional jumping on it you probably don't need to install.
Valved seats back in the day were induction hardened -- but if the valve seats are ground below this "hardened surface" erosion may occur.
I'm sure others will chime in on this ...
