Go down to Part 5. They have some pretty detailed instructions.

Ok thanks guys!
I take it that just because they went to 10 4" bolts that the install ansd torque spec didn't change.
I sure hope I don't snap any bolts off.
22 lbs, 90 deg on the first passs then another 90.
There was something else about an additional 25 or so degrees on two of the bolts.
YES?
UPDATE. the part # 012498545 does not work on a 2005 LS6 (mine) out of a CTS-V.
All I need to know is:
1. Does part #12560745 work for a replacement head bolt?
It is threaded all the way, not like the stock bolt.
2. Is the install the same? I don't want to break off a bolt, especially when I add the 50 degree final pass on bolts 9&10.
