pred rotc6 head valve guides help

I have a new predator head and the valve guides are 5mm, is there a way to put the Honda guides inside the head to make the valves 5.5mm.
The guy that does my head bought 5.5mm valves and I need them to fit
Just run it with the stock valves . Their big enough stock and come with the auto style retainers . And from what I read on Bobs4cycle are fine .
Thanks fellas I seem that they sell the 5.5 reamer so I just bought that, Dave I can't run stock valves I'm building the baddest small block in Michigan over here lol
