They are tight because the steel bolts seize in the aluminum intake.
Don't use locktite, use anti-seize. I do , on every steel bolt in aluminum, and even on steel to steel if there is a possibility of corrosion.
15 ft/lbs is about right, that bolt is a 6mm in aluminum, much tighter and you pull the threads out of the aluminum!
