yep...need a 12 point socket, not the normal 6 point, 10mm I think.

i had the same problem. its either your using a cheap 12 point socket or an old one thats been put through hell.

i went and bought a new one and problem was solved. my second build time i went with stage 8's locking fastners. 6 point and they have an 7mm allen head in the middle. work really slick

Where did you find these bolts?
ARP's catalog only lists a 12 point stud kit (in stainless) for the LS engine.

I wanted a bolt kit but couldn't find that ARP made one, which surprised me.
