Glad you enjoyed the humor. I try to use it sparingly, as it sometimes doesn't go over all that well.
The JH exhaust gaskets are individual, one per cylinder. I've seen composite and solid copper ones. The composite gaskets probably seal better. Installing them requires jacking up the engine for clearance, possibly prying it to the right a bit, undoing the header and sliding it off the studs in the head, removing any residue, then slipping the new gaskets in place. A bit of aerosol exhaust gasket sealer applied to the gaskets may keep them from falling off just before the header is slid into place.
As you note, the tricky part is getting rid of the residue. If a scraper and wire toothbrush don't work, you can try a small rotary wire brush on the end of a flexible shaft such as the ones used for Dremel tools.
If you have the small pattern nuts that Delta sells to secure the header in place, count your blessings, as they are much easier to remove and replace than the original factory ones. If not, it is prudent to install a set, as you'll probably save an hour of nasty grunt labor when reinstalling the header.
For reference, here's a photo of composite exhaust gaskets.
