In all fairness to the original poster, I have to say that I have had
problems with aluminum heads
in the past. I USED to have one of the click style torque wrenches that is
SUPPOSED to
click when it gets to the correct torque rating. Well it turns out that
this style of wrench is less than
reliable. I ended up stripping the threads in an aluminum head because the
wrench never clicked. :(
Solution for future projects?: I bought the old mechanical style torque
wrench that actually SHOWS
you how much torque you are applying. Thus leaving up to me when I have
reached a particular
torque rating instead of the wrench.
I highly recommend that all of you that have the click style wrenches give
them to your neighbor to use
on his mini-van. Then go buy a good old mechanical torque wrench to use on
your LBC.
