so I called ARP and talk to their Tech department.
This is what he told me.

"on a non competion motor you can resue studs up to 14 or more if no detonation occured"

"on a competion motor you can use them up to 4 times or more if they don't strech"

btw they are going to send me 1 new stud. Im going to use it to measure the rest of them and see if they streched at all. And no im not going to use them if they are ok.

im going to push a good ammount of boost on this motor and I don't want to take a chance. thats why I took them all out, when I could have just taken the one.

I SNAPPED 2 arp studs on my last build

Both snapped where the threads end on the head side of the bolt

You can feel that there not torquing though

I just pulled another 2 from my spair car and never had a problem since, never even called arp actually
