Yes. BTW, many new and some old engines had shallow water jackets.
My little Buick 215's were shallow water jackets.

The purpose of grouting is to stabilize the bottom end of the block
so the cylinders are less likely to split. That typically occurs if
the engine is turned to high RPM or has a bunch of core shift or has
been bored too far. A typical 2 bolt main Cleveland block will cap
walk before splitting a cylinder.
