Hi Gilberto,

the <<{ } \\ { }>> - construct inherits voiceOne/Two.
voiceOne/Two modifies 'graceSettings based on the _default_ settings
not the ones you tried to insert.

As a (not tested) workaround you may try:

\layout {
  \context {
    \Score
      $(add-grace-property 'Score 'NoteHead 'font-size -5)
      $(add-grace-property 'Score 'Slur 'height-limit 0.9)
      $(add-grace-property 'Score 'Flag 'font-size -5)
      $(add-grace-property 'Score 'Stem 'length 4)
      $(add-grace-property 'Score 'Stem 'length-fraction 0.8)
      $(add-grace-property 'Score 'Beam 'beam-thickness 0.3)
      $(add-grace-property 'Score 'Beam 'length-fraction 0.5)
  }
}

{
  \grace c'8 c'1
  <<{\grace c'8 c'1}\\{\grace s8 a2 g2}>>
  %% \grace s8 is inserted to workaround another instance of issue 34
}

HTH,
  Harm
