You can try Block Export Import module, It will help you to import block to remote site.
This module allows users to export all system specific blocks (are those blocks which are created using Drupal interface add block functionality) and then import it into another Drupal installation, or on the same site.
No additional configuration is required to export/Import block(s). Also this module does not create any table in the database. Therefore it will not effect the application performance.
