yes you are right , I opened the head before I took a look at the replacement bolts. I dont have the manual. do you have it ? can you tell me what is the torquing procedure for the cylinder head ? is it the same as the LS heads post 2004 ?

The torqueing order should be the same, but the actual torque figure should be able to be googled.
