Replacing the injector seals and the threads for the injector seals are stripped out. Someone in the past had already resized them to a larger bolt, but those are stripped out as well. What should I do from here? I was thinking about melting down some aluminum rod, filling the hole with that and then tapping in new threads. Would that be a viable solution?

That is an appropriate repair. Keep in mind that the head is an alloy so pure aluminum will not be as strong. The best I have seen is aluminum welding and then retapping.

^^ General idea is sound. In this particular case, I would actually recommend a Time-Sert, which takes up even more space, given that someone apparently had widened the hole earlier. Why people do this instead of a proper repair, I wish I knew. OP, you can recover from the previous owner's apparent butchery.

Time-sert is a good solution, if only current enlarged thread is not already too large.
