It doesn't matter. You can see what ARP recommends on their website, but mostly anyone with ARP head bolts used on aluminum heads torque them between 65 to 70ft. lbs.

i dunno my mr gasket MLS units have no up/down side, you can throw em on however you want. I wouldn't go more than about 70 ft lbs with 30wt on a stock block. an aftermarket block you can go up higher, **** some fast nitrous lsx guys were doing over 100 ft lbs on aftermarket 4 bolt blocks to keep the heads on em.
