Dick:
Actually, it is the gasket manufacturers that have the most to
say about this.
I believe that retorquing pretty much disappeared by the end of
the 60's
or so. When I look at GMHPP catalogue for example, all the gaskets I
find listed specifically
state "No retorquing necessary".
Whether or not you need to retorque depends on what the gasket
is made of.
Modern materials have pretty much eliminated the need to retorque,
except possibly
for some special applications.

Thanks, Dennis. I guess I was just hoping that you had some SAE paper
on this subject tucked away somewhere that showed retorqueing is or
isn't necessary to ensure that gaskets don't blow prematurely. Since I
have been considered somewhat of a Triumph guru, I like to protect this
honor by getting the best info possible on various subjects. AS stated,
I find no problem in not retorqueing, after doing it correctly the first
time a new gasket is installed. Others swear that gaskets "shrink" but
offer no tangible evidence of this. My next step will be to recover a
used gasket and compare it to a new one, to see how much crush has taken
place. For whatever that's worth!
