Could mean a hundred different things. But by far the casting number is more important (located under the valve cover, 8 digits long).

It's the GM part number.

Any reason you'd think the W2 would mean anything special?

I think I have seen that before, no idea what it meant though, believe it was a stamp not a cast in thing.

I would not worry about it.

An LT1 bock can be recognized by the number 327 cast into it.
