There is no way for that area to be 100% sealed and holding pressure even when head bolt washers are used
, and the the few times that I have had a blown head gasket it was not from that symptom it was from head bolt holes that where not cleaned out enough to allow accurate torque readings

My hypothesis, and thats all it is, of oil laying in a blind hole has nothing to do with the head of the bolt area
simply put a head bolt in a blind hole and excessive amounts of oil cannot maintain the same space the oil has to leave the area before the bolt can be run down fully, this takes a bit of time like oil leaving a pumped up hydraulic lifter, if a person was to quickly torque a head bolt and move on the bolt might not be putting a clamp load on the head
only a possibility food for thought not a direct diagnosis and yes head bolt holes should be chased and clean with minimum lubrication to get the job done
