Is it heads or head? Google told me both are okay. What do you think?
I will blow your head[s] off if you don't tell me.

I will blow your head[s] off if you don't tell me.
It simply depends if there is more than one person. ie. plural.
I think in most cases you would be threatening just one person, so it would more likely be without the "s".
I will blow your head off if you don't tell me.
If you are in fact threatening a group of people and are prepared to blow all their heads off then you need the "s". And "you" is now plural.
I will blow your heads off if you don't tell me.
