How much torque do you need for a head bolt?
The studs need to be torqued into the case prior to reassembly. Install two nuts, back to back on the upper threads then torque the studs into the case to 120 to 150 inch pounds. Install the cylinder being careful to get the piston rings aligned with the pins in the ring grooves and into the cylinder.

How much torque do you need for a head gasket?
A: the bolts are torqued evenly B: there is enough pressure to hold the head gasket in place and prevent blowouts. i know it’s a bit over what is recommended for the head torque, but really if you go slowly and uniformly. you’ll be fine going to around 25-35 ft-lbs. just make sure you have a good torque wrench, and slowly torque it.
What are the torque settings for head bolts?
SOURCE: head bolts torque settings According to my haynes manual for G-S reg, 1989-1998 it goes as follows, Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head. Stage 2:-Tighten all bolts to 40Nm or 30lb ft. Stage 3:-Angle tighten all bolts a further 60 degrees. Stage 4:-Angle tighten all bolts again a further 60 degrees.
What does torque mean when tightening bolts?
When you tighten a bolt in a bolted joint, you use a twisting force, called torque. Torque is related to bolt tightness , but many additional factors – such as friction – combined into a single “nut factor” can have a significant impact on the relationship of torque to the tightness of the bolted joint.
