Why didn't I think of that. Right here on page 27 & 28 - http://iihs.net/fsm/?dir=159&viewfile=Engine.pdf

Answer...18 lb-ft for the nuts that go on to the studs. That's half the answer.

The other question is how much to tighten the studs that go into the block (the studs that the aforementioned nuts go on top of). Must not be very tight because those studs only have a 4mm head on them.

I also noticed the cam overs only have 89 lb-inches (not lb-ft) on them. That's not tight at all.

I'm scared to death of over-tightening a stud into the aluminum block. Would be a serious #*$%^ to strip out a header stud hole.
