16 volt system with alternator.

I wanted to get some input on a 16 volt system with alternator. Late model F body stocker with 16 volt batteries and powermaster XS alternator. I also have a voltage step down box 25 amp continuous. My question is if the components will handle the 18.6 volts while charging. I realize the gauge lights and small things will need to be stepped down but what about the injectors, starter, Fast XFI ECU, MSD7AL,e shift and valve body,etc.I have heard those components will have no issue at 16v but not sure with the added charging volts Thanks in advance for any help.
