Just spoke with a tech at Vivid racing (in Tempe, AZ), they recommended ARP bolts. They're actually studs that you thread into the hole, put the head on, and then tighten it down with a special bolt. According to them, they're actually stronger, and are used mostly in racing/performance applications. They won't be here for a couple of days though...

I hope it works. One of the shops I talked to told me if the threads in bolt hole are tweaked, then I'd need a new block. I'd rather not go that route...
