IIRC, the head bolts are 'torque to yield'. Tighten in sequence to spec, then 1/4 turn????

Aftermarket gaskets are torqued in steps up to 42 ft lbs and OEM gaskets are torqued to 7 ft lbs then turned a 1/4 turn.

Update.
A pulled stud is the problem, none of them on that cyl seem to have thread inserts, certainly not the one that pulled.
So any more advice?
Can an insert be installed with engine in place, (I hope)?
Is a new stud required?
Any info is helpful.
I've already removed head and cyl.
Thanks

While I have not had to deal with this problem (knock on wood), most people have repaired this without pulling the motor further apart. Timesert or Helicoil it and go. Some of the usual tricks like using a vacuum, lots of grease when you do it would help keep the crud out of the bottom end. Your original stud should also be OK to reuse.
