There are plenty of detailed explanations to set up valvetrain and what the measurements mean. You should find the most reliable information as to torque specs and installed heights from the manufacturer who made your parts. They should have been included in the instructions, unless you bought them all used or you didn't bother with them either.

Apply the moly lube that came with the ARP bolts to the threads, as well as under the head of the bolt and both sides of the washer. Only a light coating is needed. If you don't have the included moly lube, put some motor oil on the threads.
Torque all 15mm bolts to 30lbft in the torque sequence listed in ls1howto.com.
Do a second pass at 50lbft, and finally a 3rd at 70lbft.
Finally install the 5 smaller ARP bolts and torque them to 22lbft.
