Some clarification.
T800 is not likely to have a heater matrix bypass installed as part of the FOHE, the modification concerns creating a flush fitting matrix where ice cannot accrete to the protruding ends of the matrix.
Where T800 is different, is FMU spill return. It does not recirculate back around the FCOC whereas the GE, P&W and all RR architectures (except T800) recirc spill back through FCOC.
