  I know this comment will go 'against the grain', but I've re-used head bolts with no ill effect (and many thousands of miles
  afterwards).

  I've reused headbolts as well.  Unless they are overtorqued, they are not plastically deformed and may be used more than once.

  Umm, all head gaskets have metal rings surrounding the cylinders, and as those rings are compressed upon torquing of the head bolts,
  successful re-use would basically require that everything went together *exactly* as it was before removal.

  Head gaskets are cheap, use a new one.  Reusing ANY gasket is false thrifty-ness.  (aka, cheapass, with a smaller case c)

  Be advised decking will raise the compression ratio.  The impact is more severe on engines that have higher a pre-decking
  compression ratio. 

  Only a small fraction of a point.  I'd be more concerned with retarding cam timing....but, if ya' gotta', ya' gotta'.
