Actually you really do not need to run it for 10 minutes because it is in fact a roller cam. There is no break in of a flat tappet cam because it rolls around the cam. There is no metal shavings that are coming off the cam from the roller. If there are you have some serious problems. With my rollers I usually run it for 500 miles then change it.
