The best reference I have at hand is The Feynman Lectures on Physics, Volume 1, chapter 35 (it's about the physics of color vision). The spectral sensitivity curves are on page 35-9.
For an on-line reference, Wikipedia's article on the CIE color space (http://en.wikipedia.org/wiki/CIE_1931_color_space) looks (currently) pretty accurate, and describes the 1920 and 1931 experiments on indistinguishable color spectra.
Note the difference between sensitivity at a specific frequency and total response to different spectra; It's the latter that can be metameric. (And I still believe that non-black-body radiation can be equivalent in human response). At this point I think it's more that you don't believe me than that I'm being unclear...
