Adapting heads to different body necks is a crapshoot, especially when crossing manufacturers. I did a Phicen version of Scarlett Witch a while back using a Phicen body, 3rd party Olsen head with red eyes, and some extra Hot Toys hands with effects with no issues. Heads can sometime be problematic. Is the head the video game Peter Parker? If it is, I have one and can check the neck adapter it comes with tonight. I'll check this thread throughout the day for your response.
