True they are pressed in BUT they also align the camshaft bore in this
instance.
Unless you can be 100% sure they go back in the exact same place to keep
the cap aligned I wouldn't move them. Nothing like wiping out a bearing
real quick.

For a head or transmission case I wouldn't worry much, but for a cam or
crank bearing all bets are off.
