Pretty sure early/'54 239's had a timing cover for a smaller water pump and later engines used a larger one. A 272 like you have would be the larger one.

Compare the water pump size in these photos to what you have. Notice the EBV casting number prefix in the 2nd photo. It doesn't mean the timing cover is on an EBV (239) engine.
Casting number prefixes weren't changed unless that individual part had to be redesigned. The same part was often used for up to several following years in similar applications.
