Experiment E06007 at Jefferson Lab measured cross sections for the $(e,e'p)$ reaction at constant $(\textbf{q},\omega)$ for Q$^2$ = 0.81 GeV$^2$ over a range of missing momenta from 0 to 500 MeV/c. Spectroscopic factors for states near the Fermi level are typically in the range of 0.65-0.70, a feature usually attributable to correlations. A consistent description of nuclear structure requires that these correlations should also have a significant effect on the strength of high momentum components of single nucleon states. Cross sections for missing momenta from 300 MeV/c to 500 MeV/c for the $^{208}$Pb(e,e'p) reaction going to the low lying states of $^{207}$Tl will be presented and compared to theoretical predictions using various prescriptions for including correlations.
