06 f350 with cracked exaust valve seats

My question for this topic, has any of you had a machine shop tell you that he would not recomend machining the heads for seats?
Have any of you just machined the cracked seat to seal the valve without replacing the seat?

They make hardened seat for that purpose. Find a new machinist.

^^^ Sounds like good advice. Just had my heads done, had cracks in the valve seats, a valve job, hardened seats and $1,500 later, I'm good to go.

A machinist put a post on here a while back showing what all they do to a set of 6.0 heads when they rework them. He had some very good pictures showing what all they did to them and explained why.
