Thank you. If for instance there was a header to replace and it was an RFC defined header - would this work? request_header_replace X-Sophos-WSA-ClientIP %SRC Is %SRC a valid parameter ?

There must be a copy of the same header removed from the request in order to replace. Additionally this is only possible in current Squid with registered headers (RFC defined). Unknown custom headers cannot be replaced like this.
