Not a good idea.
When the word stretch is introduced to any type of hardware, you ultimately assume it's a one-time-use item.
I've been dwelling over the proper torque sequence for the head in the FSM; it turns out the return to 0 after the first step is simply because these bolts stretch. The initial stretch affects the overall torque, while the second torque instruction seats the head studs (10 ft/lbs more) indefinitely. Reusing these bolts is not a good idea.. You're almost guaranteed to see signs of warping.
This is where ARP bolts are handy, as they're reusable and do not stretch, this why 3 even torque sequences across, and no return to 0 is sufficient for torquing the head.
In other words - just buy the proper studs and be done with it. Cheap insurance.

done it before on my mr2, 2 months after when i put in a new turbo i cranked the boost to 21 psi and head lifted....so iono..for $100 i'd rather have the reassurance.Leave a comment:

stock head studs reusable?
I have been doing research for my upcoming engine overhaul, and from what I have read, these stock torque to yield/angle torqued head studs can't be used again due to stretching, theres alota debate on this....
So I want to confirm if anyone have reused their head studs or whether or not its a must to get new oem or arp ones.
