I can't tell you with that coil as I have been using the 1 Ohm coils and RBA head at 1 Ohms with a 70vg/30pg juice.
When not used for a couple of hours, I get the gurgling for a couple of vapes then it clears itself.
You could try using a higher vg mixed juice or higher watts to see if it stops the gurgling after a couple of vapes.
