Proper Head Installation

[Rich in Tucson]

Not necessarily germane but I acquired a rebuilt and maybe never run engine with perfect 2-thread exposure of all of the studs which were not originals. I removed the head to install a new Brumfield head and every stud came out of the block and none of the green Loctited nuts came off the studs until I heated them. The rebuilder Loctited the nuts to the studs before installation in the block to achieve uniformity and presumably had to use a little bit more finesse to torque the head on the coarse threads.
