The way extensible symbols work in TeX makes it hard to get an exact prescribed vertical size without resorting to defining your own macros to put together symbols from existing fragments. With something like \left(, the vertical sizes form a discrete sequence and the precise behavior of \left depends on two parameters, \delimiterfactor (an integer) and \delimitershortfall (a dimension)---see the TeXBook. Perhaps it will be close enough to say $\left(\vrule height 52.5pt width 0pt\right.$ (The math axis is fairly close to 2.5pt for a number of fonts.)
