Can you just hook up the tach to the tach lead on the HEI cap?

Does it just work or does it work/read correctly?

Any cures to make the factory tach happy with an HEI system?

yes they do work. i installed a tach dash in my 72 with hei and all i had to do was plug it in and run me a hot wire down to fuse box (since i didnt have original tach factory wiring). works like a charm.
