I am more concerned on who will do it. No one in nh does that stuff
A short drive from NH down into Mass and you will find Scott Hovey's MassDiesel shop.If Scott can not do the work then no one can in New England.

first it will drop the compression and make it harder to start in the winter and second marine gaskets dont seem to be quite as strong under lots of boost and or timing. just my 2 cents
If nothing is taken off the head when it is done(and I highly doubt that will happen as every used head off a 6BT is off enough to redeck)you will loose a tad of compression with a .020 marine gasket.The marine gasket is stronger than the original and will take as much abuse as you can give it IF the head is installed and the PROPER retorques are done.As for cold weather starting,mine has had a .020 gasket on it since the first head job and I run with more than 20 drgrees of timing with no cold start issues.The truck is my daily driver and it sits out all night long during the winter with no aid of being able to plug it in and when I come out,cycle the grids and twist her off she lights and goes.

Why did the install of an exhaust brake give the excuse of o-ring of the head? Has to be more to the story than that.
