Yep - two of them. I read some sort of warning once about cleaning a block during rebuild and that the two steel balls in the upper valley area - under the intake - need to be driven out through the main bearing oil holes.
Here is the question - will they drive back in and stay there or do I need to drill and tap the holes and keep the steel balls for paperweights? Maybe a screw in brass plug?
