Hi Achilleas,

There's gr.skiphead(sizeof_item, nitems_to_skip)

/*!
 * \brief skips the first N items, from then on copies items to the output
 * \ingroup block
 *
 * Useful for building test cases and sources which have metadata or junk at 
the start
 */

class gr_skiphead : public gr_sync_block
{
  friend gr_block_sptr gr_make_skiphead (size_t sizeof_stream_item, int nitems);
  gr_skiphead (size_t sizeof_stream_item, int nitems);
