What Sean's pdf says and what I believe to be correct is your original post is missing a second round of 1/4 turns.

yep, after your initial 90, you do another 90. The M8 bolts are torqued to 17-20lb ft.

thanks for all the help guys, car is up and running he got it for 800 bucks with 50k miles.
after binging it home i did a compression test and 2 cylinders were 0 on bank b so i took the valve cover off and noticed a failed secondary chain/tensioner which meant bent exhaust valves.

What did you do with the bent valves cylinder head? use another head? I've got to ask if you replaced both secondary tensioners or just B bank?
Sounds like a bargain, good man!
