They are to give access to the internal oil ways when they were
initially drilled. The bulge isn't the cam, it is the oil gallery,
the cam is above that.
The oil gallery is a tube which runs from front to back of the engine
and distributes oil to the main bearings and also to the cam and to
the top of the engine. To enable these internal oil ways to be
drilled, holes must be made in the outer casting of the block. These
are later plugged with bolts and copper washers.
How do I know so much, you ask? My engine is currently spread all
over the workshop!!
