1JZ Head bolt torque & sequence
I've been searching...and searching..and searching. i've found basically nothing that helps. I'm tired of sifting through hundreds of posts and not getting any clear answers. So now I'm posting..and hopefully this post dosen't result in just another wasted search for someone else.
I'm installing a new head gasket for my 1JZ-GTE, and I need the torque rating info & sequence, which to my undertstanding is identical to the 2JZ-GTE, so I can reinstall my head.
I've had trouble finding 2JZ-GTE cylinder head bolt torque info , and lets not even mention the 1jz info. The shop manual at 1jz.com only has disassembly info, not reassembly or torque steps sequences.
So if someone could direct me to a site, picture, manual, or anything that shows me the exact torque settings & sequence to re-install my 1jz cylinder head, it would be much appreciated. Thanks.

Appreciate the links guys. The 1JZ.com and MkIV links only show the removal of the cylinder head, and not the installation.
If someone could shed some light on this, and let me know if the 1JZ-GTE/2JZ-GTE (and 2JZ-GE?)torque settings & step sequence are identical, that would help me out a lot.
I own all of the factory SC service manuals, I just don't know if the 2JZ-GE and the 1JZ-GTE have the same torque step sequence.

Well, I found some old files i saved a long time ago on my hard drive that i overlooked. i guess this is what i'll end up using. for future reference and searches. I believe the 1JZ-GTE applies to all of these specs, but hopefully a guru can make the final judgement on that.
Not sure which one of the flywheel pics is the removal / install..(top / bottom?) But it shows the main bearing studs & cylinder head bolt install..which obviously the removal is the reverse of.
