[DeTomaso] Mayo. (head bolt torque)

[Ken Green]

Jack,
 
    I retorqued all the head stud nuts on the engine I'm checking out, and nearly all the outside nuts were around 90 ft-pounds versus 105.  The head stud nuts inside the valve covers were all very near 105.  Is that common?
 
  Several of the main studs were low also, but all the rod studs were about right.
 
Ken

Incidently, Dave- head gaskets can blow between cylinders and from a 
cylinder to a water passage, INSIDE the gasket sections if its a multilayer 
gasket. Both these may not leak water outside the block. I just had that occur on 
an engine here. Noce the intake & heads w ere pulled, externally there was 
no indication of a blow on the gasket but there was enough pressure in the 
water system to blow a 2" hose off the water pump. That was the owners first 
clue... It took some very careful looking to see what had happened. And it 
was all caused by a single loose headbolt. Good luck- J Deryke
