To recap:
The head and block was surfaced.
You have replaced the head gasket twice, because of head gasket leaks.
Did the leak occur right away? Exactly where is it leaking?
What year engine do you have?
What engine work was performed at the time before the first head gasket leak occurred?
What brand of head gasket did you use?
What torque setting did you use on the head bolts? Did you tighten them in sequence at half the final spec before you tightened them to the final specs?
Did you try to re-torque the bolts after engine warmup?
I had a 235 full pressure engine which seeped oil from the head gasket on the distributor side of the engine which was corrected by re-torquing the head bolts after the engine reached operating temperature.
There has to be a logical reason for why you are having this problem. Adding stop leak may fix the leak, but it will not solve the mystery. I like solving mysteries. It helps avoiding similar problems in the future.
