    P0141 refers to the bank1, sensor 1 heater circuit.
    P0161 refers to the bank2, sensor 1 heater circuit.
    P0171 bank 1 system too lean.
    P0174 bank 2 system too lean.
    Get the system checked out by a Corvette or GM specialist. I doubt that all 4 oxygen sensors failed unless there's excessive oil or coolant in the exhaust stream.
    If you want to find a specialist, here's a directory link for you:
