As I got into this, my ac delco digital torque gauge with socket, didn't fit the back head bolts. Then I tried using my torque wrench, but it appears that this does not click in reverse (I tried around 100lb based on other bolts, didn't get a click and tried at a lower value of 30 and did not get a click, so the 4 bolts at the back of the head don't have values. But, my headgasket leak is occuring into cylinder 2.

Here is my block. You can see the HOAT pooled up in cylinder 2:

Machine shop said head warp was less than .002". They decked the head .005" to get rid of impressions left by the previous headgasket. Leaking was definitely occurring to the outside of the pistons, between water jackets. When I torqued the head, the order I used was the one in the image, having not seen the text in the FSM saying to jump all around using a different order. That's a really poor job by the people writing the FSM, labeling the bolts one way only to torque them in a different order in the text.
