Glad to see you solved the problem which is what you suspected originally, but curious as to why the coolant tests didn't show the results. I have a very similar crack (the one @Tinker pointed out) between one of the head bolt threaded holes and coolant passage and was also told not to worry as these types are common. One of my rebuild books says the same. Machinist is wrapping up the end of this month with my short block, and I will check with hi again on Friday. Hard to tell from the sequence of pics, but wouldn't the crack into the cylinder head be the more worrisome?
