this is copied from the instructions you get with the arp kit, although i left mine overnight and then rechecked and retorqued as needed
1) To ensure proper thread engaement and accurate torque readings,
clean and re - tap, if necessary, ALL threads in the block.
2) Clean and insoect all hardware proir to installation. Look for obvious
defects or shipping damages, plus proper fit, length and dimension.
3) a. If cylinder head studs protude into water jacket, lubricate the block
threads of the studs with ARP THREAD SEALER.
b. If cylinder head studs protrude into blind hole, lubricate the threads,
nuts and washers with ARP THREAD LUBRICANT or 30wt oil.
c. Screw studs into block "HAND TIGHT ONLY" .
NOTE: LOCTITE MAY BE USEED IF A PERMANENT MOUNTING OF THE
STUDS IS PREFERRED. THE FASTENERS, HOWEVER MUST BE
TORQUED PRIOR TO THE LOCTITE SETTING UP.
4) Intsall cylinder heads and check for binding or misalignment.
5) ARP recommends using the ARP MOLY LUBRICANT or at the very least,
a good quality Moly Lubricant as opposed to motor oil. this is due to
higher friction on the studs aswell as inconsistances in the clamping
force of the fastners when moto oil ( or low quality lubricant) is used.
PRELOAD (TORQUE) RECOMMENDATIONS:
Torque values are based on 75% of fastners yield strength. Use the manufactuers torque sequence but do not use the engine manufacturers torque specs.
Torque the nuts to 81ft lbs for ARP MOLY ASSEMBLY LUBRICANT
( or thread sealer) or torque to 105 ft lbs with 30 wt motor oil.

the only thing i will add is do not get carried away as it has been known to rip the threads out of the block .

I would never use these again they cracked my 205 block... use either std head bolts or proper long stud kits which can only be used on 200 blocks.
A well respected tuner on here said theres 17 thou of expansion and contaction of a yb head so you would always be torquing the head up..
