		As the title says really, anybody got a Haynes they can take a photo of or copy the info onto here for me? Tried searching google and pug306 (why did I even bother?!    ) but found nothing....
 
At a guess for the tightening sequence, id say its something like....
 
9  3  1  6  8 
7  5  2  4  10
 
So pretty much working from the middle out, and go diagonally from left to right and right to left, correct?
 
Thanks, Dan.

		The torques go as so: 
 
Pre-Tighten to 20 NM. Tighten a further 60 NM. Tighten a further 220° 
 
That order is pretty much there, it's not 10000% imperitive on the order, as long as you don't do all the back ones, then all the front ones, or similar, it'd be fine... 
 
EDIT: 
 
It's: 
 
8 4 1 5 9 
7 3 2 6 10 
 
Imagine it in a spiral outwards...

		Cheers Ruan. 
 
Just found an answer on wiki answers, obviously cant take that as 100% true but it says 
 
10  6  2  3  7  
09  5  1  4  8 
 
Which isnt far off what I meant, just that goes clockwise, working outwards.

		Oh and potential silly question here.... 
 
Is it worth putting an additional 20° or so on each bolt considering the head will be up against probably double standard boost and generally higher cylinder pressures, or not?

		This is what I had : 
 
Order- 
 
8. 4. 1. 5. 9 
7. 3. 2. 6. 10 
 
 
Torque- 
 
Stage one- 20Nm/15lbf ft  
 
Stage two- 60Nm/44lbf ft  
 
Stage three- Tighten 180 degrees
	 
	
	
On the 306 waiting list.

That's pretty much what Ruan said    ^^ but as Ruan said, last stage should be 220* (and a bit, just make sure they are all the same)
 
And again, it doesn't really matter on the specific order of tightening as long as you start in the middle and sprial out as both Ruans and Dans second one do

		Won't do anything... The bolts are stretching with that final 220*, you won't get any more clamping force, you'll just stretch them to more plastic deformation... Leave them, if they give problems, then give it another 90*... That's what I've done...

		Righto, cheers all!  
 
The head is currently on the engine but none of the bolts are tight yet because we ran out of sunshine last night. Tonights job is to get them all tightened and then crack on with putting the rest of it back together! :o

Was the head OK in the end, I haven't read the thread...

		Yeah it seems fine. Precups on cylinders 2 and 3 still have tiny cracks in them but it pressure tested fine!

		As Ruan said, Leave plenty of stretch left in the bolts for when you end up stretching the cocks in situe!

		50 used spare bolts, bang them all down with breaker, job done. If it yields swap out replace with non-f*cked bolt...  
All seriousness, ^ what everyone else has said...

It's pretty pikey for the sake of £12 for a set of bolts... The ballache involved if it's too stretched and you only realise when you've shagged the gasket is not worth £12 IMO.

		Quick question while were all here talking about it........ 
 
If some uprated headbolts were to become available in a few weeks/months time, would it be possible to replace the current ones if you removed and replaced the bolts one at a time?

not really no, you would have to do the gasket again really!

		Mmm, thought as much. PITA. 
 
I just got the idea from people replacing split rim bolts one at a time to save having to completely strip/re-build the wheel.

		Nah, it's fine, replace them one at a time and it's no problem, long as you do it up correctly again, it'll be fine... 
 
I've replaced the bolts on their own in mine from when I've stretched them too much, once you put in new ones it's fine again...

		You can always tell when you've overtightened a bolt, and i've overtightened many headbolts before... I probably scrap 3 or 4 off when tightening down just to get it on the edge... but they are all used so who gives a f*ck, and then never have an issue after that.
