Something like this might work. I wasn't sure which way you are going but the Oracle package dbms_lob will convert varchar2 to various BLOB, LOB, CLOB formats.

You might need to use a temporary table to pull source data to target side first if there are problems with the database link.

insert into database.target_table@DBLINK(text1, text2)
select 
  dbms_lob.substr(s.text1, 4000, 1),
  dbms_lob.substr(s.text2, 4000, 1)
from 
  source_table s;
