Default Coolant crossover bolt torque?

Anyone have the spec to hand for the 4 bolts that hold the crossover down? Also, do they need to be thread locked?

The torque spec for the M8 bolts is 20nm or 15 ft.lbs. Threadlocker is not necessary but anti-seize is.

IIRC those are to be tightened in 2 stages (at least on the S4's & GTs). 1st stage 10 ftlb, second 15 ftlb.

And snug them progressively left and right side so the o-rings squish nice and even. They do move side-to-side a snick as you tighten them to the heads.
