Should be able to pull them out with your fingers... If they're down in the bore too far you can pull them up carefully with a curved pick hooded under the retaining ring that holds the pusrod cup in the lifter. Last thing to do before you fire it up is pre oil it....Then just hope for the best on the cam break in.... I've given up on flat tappet cams, seen too many wiped out too fast. All rollers for me!!! good luck, should be fine.
