Re: Should head bolts be lubed or un-lubed? What about thread sealer?

This doesn't make sense to me. Although I'm far from super-experienced,
my experience tells me that there's at least one variable involved here,
and that's the condition of the threads. I'd bet a shiny donut that
a cold-rolled bolt into a hole tapped by a dull factory tap would take
more torque than a freshly-cut bolt run through a die would when put
into a freshly-tapped hole. Seems to me the engineers would want to
do away with a lot of that variability by lubing the threads. But that's
just my uneducated, empirical observation.

Not to say that you're wrong, or even that you're at fault in any way,
just that it doesn't make sense to me.
