Hi,
While trying to install the CI Alum head using ARP studs, this happened:
Basically the block cracked while I was torquing the studs, I respected the assembly order as well as the torque specs. I don`t think I applied too much torque, I tend to believe it`s metal fatigue combined with the way the studs are built, they are thicker on the upper part which I assume makes them prone to eating inside the lower part due to increased friction.
I wanted to check if anybody else experienced something like this before, and what is your advice?
I got another engine block and will start working on it soon, however now I`m super reluctant to using studs again. I`m thinking of going for bolts, anybody has any experience with a similar install?
Thanks in advance,
Cristian
