Here is the official response I got from Cosworth:
"This particular stud has a tensile strength of 240k psi.* At the same torque setting as the ARP2000's, you will see similar clamping loads.* The advantage that you'll see with our stud is that this setting will put you farther from yield than your previous stud.*

The torque we recommend is what we tested with and found to have good sealing.* You could raise this torque setting if necessary, but note that this could affect sealing by distorting the aluminum head.

Best regards
