I have Volvo D12D engine with broken valve seat and bend valves on the same cylinder. That will be fixed, but can the cylinder head be resurfaced?
you probably need a machine shop to answer that for you.
The machine shop can grind, but is allowed by Volvo to grind? It has overhead cam and i might have problems with the gears.
The head should only be milled if a thicker head gasket is available.
Machine shops I have dealt with almost always have said junk if there was and damage to the fire deck 1 broken valve and they wouldn't touch it
