This is just an IMO………………..
Yes, use a good independent mechanic to do the all the labor end on the project.
But personally I’d buy new/exchange Genuine Complete heads from Cummins–Now you have a real guarantee that your head is right–No inspection needed and all will be new and built to their highest /latest standards.
Curious–How does one inspect a valve seat as to whether the next time you come off plane fast the the seat cools before the head around it cools, and it then drops?
I suspect Cummins has changed this spec as to how the seats are installed in the marine heads for this motor to help this operating condition that occurs in marine use.
