Just remember the new technology invoved with aluminum engines-termal expansion is huge and you need to contain those combustion pressures/heat if your going to change heat to torque----------- and sealing up the new thinner oils does take more precise methods-------

As for the bolts---------if they weren't tightened into an area that did the job you would be blowing out the gaskets-----and without a very PRECISE method guys would be over stressing the block threads -remember its now aluminum, not cast iron---------The old rule of thumb about 1 1/2 times diameter for thread length engagement was left behind in the 90s-or 3 decades ago------or last century---------
