  The 11mm bolts aren't stretch.  That's why they go to 65lbs.
  I have the RT-106 instructions right here.  "Torque the nuts in 
three increments using the torque pattern in the factory service
manual.  Step 1 40Nm., (30) ft/lbs.  step 2 60Nm., (45) ft/lbs.  
FINAL TORQUE  80Nm., 60ft/lbs.
  We recomment running the engine until it reaches normal operating 
temperature then shutting it off and alloing it to cool to room 
temperature, then re-torque the nuts to 80Nm., (60) ft/lbs. again."
  Then I say follow most head gaskets recommendation of a 
re-torqe after 600 miles.  (some gasket instructions say 1000 miles 
but I believe it's a misprint since most seem to say 1000 miles / 
600 Km.

  Did you check the head with a machinist's strait edge?  Odds 
are it was warped.  You only get .002" and then you're out of 
specs.  I've gone to something close to 70 ft/lbs with my Jetta's
Raceware.  I'm pretty sure the 11mm instructions were for 
either a few lbs more, or less but I haven't been able to find 
them since I first put them in the Rabbit.  Anybody have those 
handy?  :-)
