This is an old issue. Look:

== word!

== [
"Defines a user function with given spec and body."
[catch]
spec [block!] {Help string (opt) followed by arg wor...
>> fourth third :func
== [block!]
>> type? first fourth third :func
== datatype!
When MAKE FUNCTION! processes the spec, it does not leave the type
specifiers as words. Words are replaced by their values, while
other values are replaced with their datatype. For example:
>> f: func [a ["A string"]] []
>> third :f
== [a [string!]]
So, your BLOCK! above is not the word 'BLOCK! but the DATATYPE!
BLOCK!; since its type is DATATYPE!, it is replaced by DATATYPE!.
I think this should be considered as a bug, and DATATYPE! values
should be left as they are.
HTH,
