Tap Magic is a cutting oil, not a thread lube, that could explain the odd torques. I will have to try some on a bolt sometime to see how much friction diffrence there is. I know if you use neverseeze on a head bolt they wont even come up to rated torque. I know because a guy junked a dt466 block trying that onetime, pulled all the threads out. OOPS!!! lol I got to sell an engine block for that one.
