What's the difference?

I spend alot of time on the org don't personally own a powerstroke, yet. I've noticed alot of people talking about how they put studs on their 6.0L. What's the difference between putting in studs or bolts. Thanks in advance

I think the "studs" you are referring to is actually called cylinder head studs.. they are what attaches the cylinder head to the engine block... never heard of head bolts before?

The difference is in clamping force. The head studs are threaded on both ends so you will get a better clamp on the head and a truer reading on the torque wrench because you are tightening a nut down on the head rather than turning a bolt down in the block. The ARP or H11 head studs also are stronger and have a higher stretch point than the oem head bolts.

Studs are torqued to a specific value in 3 different steps. The oem head bolts are torque to yield. once you get them to a certain torque spec you turn them an additional 90 degrees to set them. Studs are reusable, the oem head bolts are use once and throw away.
