Valve body alignment on the bolts can change the clearance on the exhaust valve .
I've seen some move as much a .050" ,which can make the difference between the brake working or not.
Do you have a can solenoid or a pancake type ? ...The can type have more travel than the pancake and usually don't run into this problem .
Also the ATI case comes with red shim washers that are intended to move the solenoid out to minimize the depth the valve goes in, did your builder use any of these without checking the depth of the valve ?
