CVH head stud torque
Sorry if this has been asked before but I can't seem to find it anywhere,
Does anyone know the correct torque sequence for ARP head STUDS AND NUTS (NOT BOLTS)
there seems to be a lot of info about the bolt torques but note or studs and nuts, is it the same ?
Thanks in advance

Quick google...
Standard headbolts are better btw, proven 300+bhp
Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension.
Screw studs into the block “HAND TIGHT ONLY”. NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED. THE FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP.
Install the cylinder head and check for binding or misalignment.
Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight.
ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to engine oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when engine oil or other low quality lubricants are used.
PRELOAD (TORQUE) RECOMMENDATIONS:
Following the manufacturers recommended torque sequence tighten the nuts in three equal steps to 60ft lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
