should be on the paper in the box. make sure to lube both sides of the washer and the threads. make triple sure the bolt holes are clean and dry (ask me how i know). i think the first pass is 25 then 70ft-lbs on the second pass.

No...

You need to torque them in 3 steps. I've always used 25#, 45#, and then 70# for ARP bolts.

You also have an LS1...LT1s need thread sealant on the threads because the bolts penetrate the water jacket.
