I am reading the service manual and find that using the stock headstuds, I should torque it to 58 ft-lb in this sequence:
8-6-1-3-9
10-4-2-5-7
Then, loosen them all again in a reverse order. And finally re-tighten the loosened bolts to 15 ft-lb in the above sequence again.
What's up with that? I guess it doesn't apply to us who is using this one-bolt-at-a-time method huh?

When you are removing a cylinder head you always start from the outside and work your way in.
I think the seqence above is the right way... start at 10 and work your way to 1.
as a revision to this writeup i noticed the nuts where actually a 1/2 inch socket not a 13 mm as previously stated..... the 13mm would work but the nut is actually a 1/2 inch on your new head studs.....
umm i heard you should do one head stud at a time , cause if u do all at once u risk breaking the seal on the head and getting fluid between the head gasket and head which i heard can lead to premature head gasket failure.

one question for me........to better ensure there isnt alot of oil in the holes so as to effect how tight one stud is from another....can i just carefully stick some qtips down in there to soak up all the oil and then put the studs in......
i know that qtips sometimes leave a lint behind so i didnt know it that would cause it to be a no no.......?

yeah i did this headstud install kinda the same like described but used a technique advised by a mitsu tech......
untorqued all of them and then did it one by one from the inside to the outside......hitting 31 psi and no headlift......
but im doing a rebuild soon anyways so it really didnt matter to me.......lol
