Entire Body Follows Player Instead Of Just Head?

trying to get a NPC's head to follow the player and also be able to animate/move. however, when i use this script, the entire body moves (the head is bound to the torso, is that an issue? i don't think so) instead of just the head and the NPC cannot move or animate. "look" is used to default NPC back to position. this may be the issue, as it must default to look a certain direction, but clarification would be sweet.

stats for bodygyro: D = 350, MaxTorque = 2000,2000,2000, P = 3000

stats for bodyposition: D = 1250, MaxForce = 4000,4000,4000, P = 10000, and Position = 0,50,0.

script is below.

local head = script.Parent.Parent.Head
local bgyro = head.BodyGyro
local bposition = head.BodyPosition
local studsaway = 15
local look = game.Workspace.PellyLook

bposition.Position = head.CFrame.p

while wait() do
    for _, v in pairs(game.Players:GetPlayers()) do
        local character = workspace:WaitForChild(v.Name)
        if character then
            local distance = (head.CFrame.p - character.PrimaryPart.CFrame.p).Magnitude
            if distance <= studsaway then
                bgyro.CFrame = CFrame.new(head.CFrame.p, character.PrimaryPart.CFrame.p)
                break
            else
                bgyro.CFrame = CFrame.new(head.CFrame.p, look.CFrame.p)
            end
        end
    end
end
