torque specifications for SBC with aluminum heads/intake
hey i tried to look it up on the internet, and on this site, and didnt get much help.

what should i torque the heads to? and the intake?
also im using APR head studs

Contact ARP for the correct torque.
For the intake, start in the center, and work your way out.
11 7 3 2 6 10
12 8 4 1 5 9
Those #'s represent the order to torque the bolts looking down from the top of the intake. Usually 25-30 ft-lbs.

10......9.......3......2......7......8

Well, with rates on the move the way they are I can see why "APR" was on his mind.

thanks, i got one head on, what a bitch.
the guidplates where the rocker studs are, what do they have to be torqued down to? i had to loosen one a little to torque a head stud, and i just tightened back up pretty good to, but im pretty sure it has to be torqued.

For aluminum heads, torque them to 65ft-lbs in 3 even steps. I usually go 20-43ish-65. Haven't had a problem yet. This was also with ARP head bolts
