My view of of that photo on a cellphone screen isn't the best but it doesn't look like a '54 to '64 239/312 Y-block.
I'm not too familiar with Ford's next generation of engines but with a "352" cast on the front and that one image of the block it seems more like a 352/390 FE engine.

Edit...
Here's an example photo of the head surface of a Y-block. Notice the row of oddly shaped holes across the top for the pushrods.
