Can someone give me the torque spec in stall on arp studs? I've heard you have to tighten them three times, to what torque each time?

What about the original ford sequence, what is it for tightening the studs?

Also on the heads, torque sequence and torque spec?

Lastly, do we torque the studs at all, or at the end with the nut?

And how does everyone address the rocker arm issue because their held down by the studs, thanks for any info you have.

Run a tap down into the block to clean out the thread holes. A little brake cleaner and then blow them out. The studs just need to be snugged down into the block.

Do you run the rocker arms and push rods go down with the stud/nut as your tightening? or are they put in after torqued to specs?

When installing studs can you reuse the stock short bolts in holes 11-15 or should they be replaced with new bolts?
