I am assuming that the header in question is created by the OP's
Postfix system and captures the HELO name used by an external
client. Postfix always inserts a space.
If this header check is intended to match "far upstream" headers,
then one might indeed allow for missing white-space, but it is
extremently unlikely to be worth bothering.
