The best deal may be to see if they have the same part # as the QR25 head bolts (e.g. Altima) and then buy 2 sets for the 2.5L from Ebay.

They are torque to yield, one time use, bolts. I would not reuse them, if you do you will be pulling the heads back off very soon.
Contact ARP and see if they have some thing that will work: ARP-bolts.com | The Official Site of Automotive Racing Products, Inc.
I do understand they are troque to yield and typically only a one time use. However a few engine builders have told me it would be alright to reuse them IF they havent stretched, the motor is an 07 and only has alittle over 7K on it, never towed, never had any heavy loads othere than a dirt bike in the bed. Im pretty confidient that Ill be ok if they all measure up alright.

for something like head bolts, I would be buying a new set. I would go with ARP fasteners because they most likely will not stretch. what is the torque spec on these? do you first torque them to a setting, then go over them again to final setting? or a one time value?

I heard its something like 32ft lbs then 60degrees then 18ft lbs, not quite sure if that is 100%. I will post it when I actually find it and do it.

as for ARP, I will be them a call tomorrow. I dont want to go with OEM due to the fact I dont want to replace then when I pull the heads again, ya dig! :teethmast

Here is the stock torque values:

Tool number : KV10112100 (BT-8653-A)
Step a : 98.1 N·m (10 kg-m, 72 ft-lb)
Step b : 0 N·m Loosen in the reverse order of
tightening.
Step c : 44.1 N·m (4.5 kg-m, 33 ft-lb)
Step d : 60° degrees clockwise
Step e : 60° degrees clockwise

The ARP's will use a standard torque value, they are not torque to yield.

Thank you so very much for this info! I greatly appreciate it! but due to alot of investigation and research, I will not be pulling the heads for basic clean up and gasket matching. Just gonna slap the cams in and call it a day :teethmast

Thank you guys for all the great info as I will need in my journey of the VK56 building.
