I've been experimenting with these default header args for Org Babel source blocks.

(setq org-babel-default-header-args
      '((:session . "none")
        (:results . "drawer replace")
        (:comments . "link")  ;; add a link to the original source
        (:exports . "both")
        (:cache . "no")
        (:eval . "never-export") ;; explicitly evaluate blocks instead of evaluating them during export
        (:hlines . "no")
        (:tangle . "no"))) ;; I have to explicitly set up blocks for tangling

In particular, :comments link adds a comment before each source block with a link to the file it came from. This allows me to quickly jump to the actual definition. It also lets me use org-babel-detangle to copy changes back to my Org file.

I also have a custom link type to make it easier to link to sections of my configuration file (Links to my config). Org Mode prompts for the link type to use when more than one function returns a link for storing, so that was interrupting my tangling with lots of interactive prompts. The following piece of advice ignores all the custom link types when tangling the link reference. That way, the link reference always uses the file: link instead of offering my custom link types.

(advice-add #'org-babel-tangle--unbracketed-link
            :around (lambda (old-fun &rest args)
                      (let (org-link-parameters)
                        (apply old-fun args))))
