I imagine at a high enough temperature, alloys of lead and iron are formed. Little crystals of lead may sit within the iron, which likely doesn't melt but might allow some lead in. Still, it'd probably be metallic lead rather than the much more bioavailable ionic (salt) form, but I still wouldn't use it for cooking. Props to OP for testing it.
