No, there are complete F-1 engines in storage. They fired up the gas generator from one of them just a few months ago: http://www.nasa.gov/exploration/sys

They fired up the gas generator from one of them just a few months ago: http://www.nasa.gov/exploration/systems/sls/f1_test.html There's a proposal to build new F-1B engines to power liquid boosters for the SLS (as a future replacement for the shuttle-derived boosters that will be used for the first few flights). Still awesome to get some of the old ones back, though!
