To undo the problem:
find . -type f -print | xargs chmod 664
Note that any executable files will no longer be; if there is a "bin"
directory you may need to change those back to 755.

A better way to change just the directories instead of what you did:
find . -type d -print | xargs chmod 775

Or assuming the files were previously 755 (directories & executables)
and 644 (plain files), then to add group writable without affecting
anything else:
chmod -R g+w .
