OOOH a death star....

Done a bunch of them. Have done the factory approved method and had them 
fail again. Have also used inserts with stock sized bolts.

Now I use the stud kit these folks sell. These work and hold real well.

It is possible to buy just the studs and make your own drill and tap 
guide if you want to save a couple hundred.

Oh, while you're in there, change the primary timing chain tensioner and 
the intermediate sprocket bushing. They tend to wear faster than the 
other pieces.
