Can you do an example? Here it works (18.104.22.168.1).
>From my tests, the header is not seen only if
before REBOL  there is some no space chars
there is not a newline between the chars and REBOL 
The only difference i see is this:
script? "aa^/rebol" ;== "aa^/rebol"
script? "aa^/[rebol" ;== "[rebol"
This could be a bug.
Note also that in the embedded case the final ] can be omitted.
So i think that this is enough:
load-header: func [
"Load and construct a Rebol header object"
str [file! url! string!]
if str: script? str [
construct/with first load/next find find str "rebol" "["
probe load-header "# aa^/rebol[needs: ]"
The function return none if the header block is bad formed, like in case like
Note that script? returns a positive answer in these cases:
script? "rebol ["
so we need the attempt in the function.
