That is the question I've been kicking around.
My machinist says I shouldn't need them, as they are hardened from the factory. But then he goes on to say that as long as nobody did a valve job and ground through the hardening it should be fine.
So I'm still trying to figure out, do I or don't I?
If you trust your machinist in his work and he says you are not in need of them then don't bother. In my case i had a few that were going to have to be replaced regardless so I decided to have all my exhaust seats done. Its ultimately up to you if you are still unsure it doesn't hurt to take it to another reputable shop in the area and see what they say.
This is unfortunately one of those things that goes both ways you see varying reports from many sources that say one or the other.
