Thanks for the input. To complicate things more, someone mentioned that if I have a gasket type of plug that I am taking out and putting back in then the gasket may already have some compression to it and therefore could effect torque required or amount of wrench turn needed. Maybe in the end I will just pull a plug or two to take a look, apply a little anti seize & ballpark by feel maybe 1/4 turn in putting it back. I never knew plugs needed to be so accurate (one source attached).
