Deck height was only diferent in '69. All later years were the same for deck height. '94 and later were set up for a roller cam. The water pump intake is based on what year timing cover you use - the block is the same.

In the US, some states do emission requirements by the year of the engine block. Emissions started in '74, thus, if you were in one of those states, you would want a pre-74 block to avoid having to pass emissions.
