Exhaust brakes ???

with the exhaust brake, it will only be used during engine braking(when you are off the throttle) and so there will be little, if any, fuel being injected and burned. so EGT will be low, and the headgasket should be OK.

that is, if the exhaust brake is never used under throttle.

If you apply the exhaust brake and full throttle, all that happens is a tornado of black  snowflakes fly out the pipe, then the engine stalls.

Sounds like you have tried it?

My friend got a truck where the actuator had  been plumbed backward.  I had never had people from more than one  neighboring car complain about soot landing on them before.

Thats probably pretty bad for the engine also. What system did your friend use and electronic actuator or pneumatic actuator?

BD vacuum actuator

i hope a electronic actuator will be strong enough to stop the airflow.
