So, I screwed up 2 rocker studs on my new DRD heads by putting the shafton upside down. It boogered up the shoulder which may have not been seated fully in the first place. I bought some new studs and they are stretching. I've strectched 2 so far. The 2 studs that came with the heads are perfectly fine and have taken proper torque 5 times now. The replacement studs are stretching at 20ft lbs. I couldn't imagine I'm doing something wrong, but idk.
Anyone ever seen anything like this? I'm gonna have to get some from DRD cause he must have the good stuff. lol

| My supplier got them from bugpack. I won't name him, but I will note that he does not have anymore. He contacted bugpack and they hadn't heard of this issue. |

20 ft-lb torque will stretch a "regular grade" stud.
Apparently, those studs are not the right stuff |

| Stock VW studs torqued to 18 fp. will take quite a pounding and hold up. I think you got a set that was not heat treated correctly or made of the wrong steel. |
