Default Re: Cylinder Stud broken

For the head torque, 144 in/lb is about as far as I would go using the studs provided in the kit, if I wanted to torque the studs higher than 144 in/lb I would get the higher grade studs just to prevent one from breaking or stretching. You will know right away if one stretches because right before you reach the desired torque it'll start to turn easier instead of tighter. Torquing does actually stretch the bolts or studs, but they can also over stretch and when you remove it you'll see where it looks like a piece of taffy that was just pulled because you'll see a narrow spot somewhere on the fastener. Proper torquing only stretches the stud or bolt a few thousandths of an inch at best...
