Was wondering how many of you guy's figure
out the torque of a bolt, or stud,when you are using
an extension on your torque wrenches?

I am in the process of freshening my engine,
and ready to torque the heads, and was figuring
out the torque when using an extension on the
wrench the studs call for 80 lbs, but when you
figure it out with an extemsion on the tw the
torque valus is quite a bit less, I am figuring
it this way

length of torque wrench multiplied by the stated
torque of stud

20" x 80 lbs

Now add a 4" extension on for clearance over the
rocker stands, add the 4" to the length of the
torque wrench

20" + 4"

Now take the totals of the 2 and divide them,

20x80= 1600
20+4= 24 devide the 24 into the 1600

Now you have 67lbs average for the torque of
the studs this seems like it is low to me, am
I over thinking this or not, I have had a problem
for the last few seasons with head gaskets showing
leaks when the engine comes down for the winter
freshening, and was trying to figure out the
root cause of the problem, I feel like they
are not getting torqued enought to seal them.
by the way I am using the steel shim gasket, have
tried every trick I know to tweak them to get a
seal, and have not been successful yet
sooooooooooooo how to you do your torquing, when
you do heads??????

Thanks
