We generalize calculations of the energy-momentum tensor for classical gluon fields in the boost-invariant McLerran-Venugopalan model using the small-τ power series expansion method. Results to all orders for the energy density and pressures are given in the leading Q2 approximation and with the inclusion of estimated running coupling effects. The energy density and transverse pressure decrease monotonically with time while the longitudinal pressure starts from a negative value and increases towards zero.
