If you install the studs correct like the directions say no retorques are needed.

Correct, only need re-torques with rings.

also correct with the fire ring part :c:

so without o rings or fire rings ... no retorque ? ... never told that before ...:humm:

Nope. The rings slowly ckmpress more and more causimg the clamping pressures to reduce. The head gasket will completely compress at initial torque. Anything with rings will require atleast 3 re-torques.

for o rings or no rings I don't retorque ... with fire rings I retorque.

I was told by Dynomite Diesel here in Monroe ... always re-torque with either ... I guess its better safe than sorry .....

I think its a matter of insurance either rings ( o-ring or fire ring )..

I re-troque heads even just plain ... after a few thousand miles .. just safe that way ..... :tu:

If ypu mark the nuts you'll find that with o rings or fir rings either that when you retorque that you'll get quite a more threads each time. If you have trucks that a o-ringed I sugges you re torque them ASAP. I've got a truck coming in Monday with a blown gasket because of no retorques with o rings. If you will go do it you'll find why it is absolutely required! A factory gasket you'll get no additional thread. By re torque we're all talking pulling one nut at a time off, clean it, apply more thread lube andnre torquing one by one, right?

Absolutly ... yeah thats the olny way i know how .... ??? is there another way ?? lol
Probably the wrong way ...

So if you don't need to retorque ur head studs when using a regular gasket, more than likely my blown gasket was do to a warped head.
