I am attaching the entire process to install both heads just in case someone in the future needs more then just the torque sequence. Also, you noted this was a 3.5L. I assume you meant the 5.3L.

Also, after replacing a head head gasket or reinstalling a head, it is always a good idea to spot check the compression on a couple cylinders just to be sure everything is okay. Here is a guide that will help with this. Clearly that is not needed but a good idea.

Please see below for the process and the sequence. Looks like page 6 and 13. Let us know if you need more info. Thanks
