I'm sure this has been discussed previously, but is the head torque value listed in the service manual for lubricated or non-lubricated threads? I recently did the re-torque while hot procedure, and could feel a definite difference between the dry outside studs, and the studs under the rocker arm cover which were covered in oil. This made me think that I probably should have lubricated the stud threads when installing the head, since there were no instructions to "dry" the threads for the hot re-torque procedure. And wouldn't there have been at least a light coat of lubricant on the studs at the factory anyway for protection prior to install? My current thinking is that it's a wet value, but I would like to hear from those of you with experience in this matter.
