Which is the fastest way to heal the gap between almost-fit-objects?

Hello everyone,

I have these 2 objects, head and body that looks like this:

So, I separated the head to do stuff, intended to put them together when the stuff is done. But perhaps the head has been scaled a little bit.

I can only think about filling the vertices by selecting every single vertex then press F. Is there any faster way?

Maybe upload a screenshot of the wireframes.

so I merged vertices. Sorry for being impatient
