Nothing special about the procedure, it simply is not widely known.

Thx Max -
I looked at the procedure in the Tech Data book and wonder why the
last torque it says 30Nm + 5Nm - I want to be absolutely sure I do this
right - I wonder why they didn't just say 35Nm's?
As far as torque wrenches - I have a 3/8" click type as well as a
1/4"
drive beam bar (??) type for inch #s. But I'll take your advice and
make sure one or the other will work.
As far as doing one DV at a time, then starting the engine to test
for noises - on my 602-962 engine it looks like I'll need to remove the
intake air manifold that comes across the engine from the turbo to the
intake.
This is over the IP so will need to come off. It's not a he deal I
suppose but will make for a longer time needed.
If proper torqueing will prevent warping, I would think I can do the
3 step procedure. I've torqued a lot of heads using a multi-stage
method
followed by a 45 degree movement. Is there something especially tough
about properly torquing the DV's?
Not being argumentative - just trying to understand --
Thanks again for the help -
