Bubbling noises

Hello,

I own a 89 Turbo (no AC) and i just recently fixed a BHG, the head was machined, new bolts, used the correct torque (75 lbs), etc.
I am experiencing the following: when i turn the heater on, i hear a bubbling noise behind the dashboard and it gets stronger as i increase the revs...it looks like compression from the engine is still passing to the coolant system. Can this mean that i have a BHG again ?!? Or its the heater core?

Thanks for any help!
