Not sure if you know this,,,,,,,, but you only need harden seats for the exhaust valves.
Only 6 are needed.
Yeah ive never heard of someone putting hardened seats on the intake valves before. Don't see a need on those they are not exposed to the same heat/gasses/combustion as an exhaust valve. Also yes a valve seat may fall out but HONESTLY out of the # is hardened seats install how many have fallen out?
