As Art suggests, saclst will hopefully provide 
the header list capabilities you need.
In the short term you can hopefully get by using listheader within a script and
redirect the output to the file you want.

Something like the following script could be invoked as
sac_lh.csh "your_filename"
Note that the blank lines are needed to get all the headers and you'll
still have to edit the results if you want a particular format or to get rid of
extraneous information and blank lines.

#!/bin/csh -xvf
# sac_lh.csh: script to list sac header listing to standard out
r $argv[1]
lh inclusive on

# end of sac_lh.csh
