Yeah, I have a smaller inch/lb torque wrench, set it to 180 inch/lbs = 15 ft/lbs. Did a test with the bolt itself, only seems to take about 10 ft/lbs until it starts twisting and ready to snap.

These are stock bolts, but don't seem to take 15 ft/lbs. ???? Im confused.

EDIT: Is it possible I'm looking at the wrong specs? I'm trying to tighten the 6 bolts for the bolt holes you see in this picture:



I am using stock mercedes gaskets that go in between these and the block.
