300TDI Cyl Head Torque Specs, anyone?

I loaned my manual to someone who is out-of-town for the holidays and need to torque a 300TDI cylinder head before noon today.

Anyone have the torque specs?
Searched this site and read through a sload of posts, but didn't see any specs.
Google resulted in different specs and know it was printed incorrectly once and later updated by Land Rover.

Had the correct specs written in the margin of the manual and can't get in touch with the person who has the manual right now.

Cylinder head to cylinder block:

M10 x 117 = 40Nm +60 degrees
M12 x 100 = 40Nm +60 degrees
M12 x 140 = 40Nm + 60 degrees + 20 degrees


Hope this helps
This is from the Defender 300Tdi 90/110/130 96/98 MY manual

Was it updated to something different??

I saw those on google, but thought there was at least one more round of a degree torque.
Am going by memory and could be wrong, but thought there we 2 degree torque steps for all the bolts except the largest which took 3 degree torque steps after the initial 40Nm.

Jeff:
Where did you find these specs?

And thanks,
Happy Holidays

Stage 2 Further 60 Degrees
Stage 3 Further 60 Degrees
Stage 4 Further 20 Degrees for Bolts 1, 2, 7, 8, 9, 10, 15, 16, 17 and 18

You would hope it is common knowledge not to use an extension when torquing, but many weekend warriors overlook this. Not sure why manuals don't call attention to this.

Yeah, that sounds like stretch bolts.
I thought I read you could reuse 300 head bolts 5 times?
I just looked at some UK forums and they only talked of the 2nd stage torquing.

I have written the correct specs in the margin of my manual now.
