Default LS Motors - HEAD STUDS - TORQUE SPECS ???

QUESTION . . . When using Head Studs on an LS block ( iron LQ4, in this case ), instead of Bolts, what is the correct Torque Spec, since Head Studs don't "Torque To Yield" ?

Thanks, in advance !

The head studs should have come with torque specs.

^^^He's correct. The torque specs depend on the specific studs you bought.

That depends on the material grade of the studs. The cheap ebay studs seem to be the same alloy as the stock bolts, while ARP has at least three different alloys (8740, ARP2000, L19, etc). Each will have a different recommended torque value.
