I have one head, bought it from someone here so it's second hand, lol - there is a hole in the fiber skull near where the M16 screws into the fiber skull and I can see what looks like an indentation at the back of the canal (throat) but this head doesn't disperse the air during fun time (if the indentation is a valve, it is stuck shut) and I have cleaned this mouth/canal several times well and I can see it, and pushing on it doesn't do anything but stretch the TPE.
A hole in the base of the skill may, or may not, indicate there is airflow from the oral section into the head.
You need to test it to see if the hole is there.
First, shake the head to insure there are no liquids inside of the skull.
Second, take a toothpick and gently clean out to skull hole to insure it is not blocked.
Then place and secure the head in a mouth up position. Towels and such are the best for that.
Next fill the mouth half way with isopropyl alcohol. Stick in your finger and squish a bit.
Continue to fill up to the top with isopropyl alcohol, note the fill position and leave it alone for an hour or so.
When you come back, look at the position of the liquid in the mouth.
Finally drain out the fluids from the mouth and insert a tampon to assist drying.
If the fluid levels have gone down, then there is a hole from your oral cavity into the skull.
If you shake the head and hear fluid inside, then there is a hole from your oral cavity into the skull.
Otherwise, there is probably not a hole from the oral cavity to the skull and that head is a good modification candidate.
You can drain any isopropyl alcohol in the head by shaking the head to get it out of the hole, or just leaving it inside.
The residual alcohol will not harm the skull internals or promote mold growth.
Good luck.
Cheers!
