I had the same head on my '52 half ton. In my opinion it is a '52 head or possibly '51 on a '49 block. That head was only used in '51 and '52 as far as I know.
If I am not mistaken, my head required a 235 head gasket even though it was a 216 engine block. Also, the manifold had larger ports, I believe the same size ports as would be found on a 235.
