sunset,
If the heads are not flat, new headgaskets and bolts will not stop the problem. If the head flatness is off by more than 0.002 of an inch then the head needs to be replaced.
Here is TSB outlining proper test procedure

Are you running stock or is the engine chipped/tuned?
Hope this helps

sunset,
Well if everything is in spec and you are not running a chip/tuner, then off the top of my head, the gaskets were not properly installed when they were replaced.
Have you ever seen boost over 30 psi while towing?

If it was an inline chip/module (ie Banks, Edge, Dr.P) then you could look at the swirl patterns on the piston tops or send pictures of them to FMC engineer. The patterns are different on a chipped engine than on stock engine.
As long as EGT temps are within range the turbo is not going to change color, but you can still lift the heads with a chip/tuner and not run excessive EGT.
Maybe Matt will see this thread and have some more answers or ideas.
