You may also want to remove the rubber seal at the back of your hood. You can also try securing the hood with longer bolts and washers to increase the airflow out of the engine bay.

I usually pull that seal out. I like your idea about using spacers to prop the back of the hood up a little.

That usually will turn into a high pressure area, think cowl induction. You could be pushing air under the hood, not out.
