FYI: there are other people who have had issues, and are still cropping up. So check your bore & fitment. Slightly warped heads, off-center holes, bore size variance can all cause a problem on YOUR motor.
ARP studs are a 'race' product and checking things before assembly is part of your job building a motor... unless you have a shop do it that will warranty it.
