Suppose with more heat and stress on the bolt the hole will go worse then start to lose water.

for now it should be ok. but the thing is, when the engine heats up the ali head and the cast block will expand at different rates. this is normal. but as it heats and cools a few times the crack may travel further into waterways or oil galleries. if your really worried about it, its worth taking the head off for a deeper inspection. just try and lay off the lead-foot ways and you shouldnt have too many problems.
