Looks like that's where the coolant crossover pipe is supposed to be.... But it appears removed.

On my '04, I only have one crossover and it's at the front. At the back of each head, I have plugs. The first picture looks like the gasket is on wrong, but the second makes me question.

steam port block off that's a ***** of a spot to have to work, dealer might have it, dorman sells a kit I had to order one nobody stocked it.

Yeah, I don't imagine it's very fun to get at with the intake manifold there and I can't remember if it's a 10mm or 8mm. I bought the dorman gaskets (56390) when I swapped out my cracked heads, but that was easy because everything was already removed. Looks like ICT Billet makes replacements as well, that just use an o-ring: https://www.amazon.com/ICT-Billet-Throttle-Cylinder-Coolant/dp/B07ZG3F1SJ/
