I think head has feelings for Victor, it's just that it's more rational than heart and can see that Victor never truly loved Henry, he was obsessed with him and the idea of him being his lover but never truly loved Henry just for being himself. If Head did not love Victor, he would have left a long time ago.
Idk I think it isn't love but curiosity or entertainment and maybe some resentment
I honestly wonder if Henry's heart and head (without dick) were combined would it actually get the desired results Victor wants. Give Henry that has memories but no feelings his heart back and remove his unsatisfied dick maybe he'd actually like Victor for real.
Or
He'd be conflicted about his actions but ultimately follow his head and still be a dickhead (no pun intended)
