Look at those valve seats (M20)
Hello people,
I finally removed the head. quite easier once you have done it once already.
this pic was taken after the rebuild by the shop.. clean
no more clearance on my head because this!
intake valve is fine
shop is on holiday so gotta wait but they better change those seats free of charge...
anyone has an idea what went wrong in the rebuilt process?

You're right, it looks a bit odd. Almost as if they counter-sunk the seat during the re-grind. They really look like they sit down in a pocket. Are they the correct valves?

It doesn't look like the seats have receeded. My guess is the valves or seats were ground at an incorrect angle.
