If the steel studs were used and while cold were given a preload that would overcome the peak cylinder pressure force then when hot do you think it would be possible that the preload would increase enough to locally yield the Aluminum or Magnesium of the case/threads? If so, then the preload when the engine became cold again would be too little and could cause the head to move or lift and combustion gasses to escape.

If the cold preload is set so that it would not yield the Aluminum when hot then when cold it may be too loose anyway.

Therefore, Dilivar may allow a more aggressive warm-up period?
