Do em all at 10 ft-lbs, then 20, 30, 50, 60 (Double check final, but I'm pretty sure 60 is recommended on the TF aluminums). Don't forget ARP thread sealer on the bolts through the water jacket, and ARP moly lubricant (assembly lube) on the others. In addition to being a good/necessary idea, they will also affect torque. Do you have ARP bolts? If not, get them

I definately recommend the ARP bolts. Also, in order to get proper head bolt stretch ARP recommends that you use thier lube andtorque them down then bust them loose and retorque them 4more times for a total of 5 times. I know this may sound strange but they recommend this so that the bolts wont stretch under load andallow the heads to lift and in time pop a head gasket. Just so you know Im not crazy check out the link below.

Good find. Nothing in any of theARP or TF directions I was given said anything about this. Good thing I haven't put the valve covers on yet

i founda manual online didnt have the bolt sequence and my dad is helping me and he has put a few sets of heads on 302's. So i should be fine

is all that jaz necessary with head studs, or is it just a bolt thing b/c they stretch?

Generally it's just the torque to yield bolts that stretch.

Thats true, if they aren't bolts that are SUPPOSED to stretch than all of thats not necessary. You also dont need to tighten them down in so many steps. 3 is good enough, do 20, 40, then 60. Thats good enough. Not that its wrong to do it in six steps just unessary. Also, if you get the stretch bolts, you can just re torque them after you drive the motor and that should work too isntead of doing it so many times. Generally, once you unbolt a stretch bolt, its done for. You gotta get new ones. I would torque them down with the ARP's, in 3 steps, drive it, then just put your wrech on 60 and make sure they are all still tight and you should be good.
