There are two different PNs for those bolts, some have a very shallow hex some have a taller one. Get ahold of a good LT1 specialist GM parts supplier like Jason Cromer(sp?) and I bet he can help.

I say talk to a specialist because they will make sure you get the taller ones so this doesn't happen again.

I forget whether it was the later or earlier ones that were taller.
