Head Studs Torque Specs? What Loctite should be used when threading the studs into the block? And what should the torque be on the nuts? Thanks again. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: Head Studs Torque Specs? I take it you mean the head bolts, right?
I think they have a locktite coating on them already so you don't need to add any.
-First pass all M11 bolts = 22lb ft
-All M8 bolts = 22lb ft
-Second pass all M11 bolts = 90 degrees
-Final Pass all M11 bolts EXCEPT medium length bolts at the front and rear of each head = 90 degrees.
-Final Pass for medium length M11 bolts at front and rear of each head = 50 degrees.

If you got these STUDS from ARP, call them up and ask them. It's should be a sealant of some type if I remeber right, but my brain is going away.

Re: Head Studs Torque Specs? Assuming you have ARP heads studs..
The studs get 5 ft/lbs
The nuts get 22ft/lbs up top, and the larger ones get 65ft/lbs ( in 3 passes ).
You should put the supplied ARP assembly lube on the TOP side threads of the studs and the bottoms of the nuts.
