Blew the head gasket between cylinders 2 & 4. In process of putting everything back together, but I want to clarify what I need to do to do the job correctly.
I know I need to use new bolts and I know the torque sequence.
But what I need to know is what do I torque them to and how do I do the tightening?
Im used to doing this in older cars and tightening them in 3 increments to the final torque, but I'm not fully sure of what to do with these torque to yield bolts.
Thanks!

Re: Head Gasket Tightening
Tighten down to these specs and in this sequence.
50 N-m + 120° or 37 lb ft + 120°
===Intake===
5 1 3 6 <---Shorter Bolts
7 4 2 8 <---Longer Bolts
===Exhaust===

Re: Head Gasket Tightening
Are you using new bolts? IIRC they are yeald to torque bolts and should only be used once.. Also if you dont have a Degree wheel for the 120* you can also put a paint line on the top of the bolt as a reference and get it close.

Re: Head Gasket Tightening
Yes, I'm using new bolts. Should I tighten each bolt in sequence to the full torque, or tighten them incrementally in a couple of steps in sequence? For instance tightening all to 38 ft/lbs then 60 degrees and then another 60 degrees?

Re: Head Gasket Tightening
From what I've read, you can go either way. If it were me, I would do half first, and then go and redo them all to full spec.
