I'd recommend NOT drilling out the factory bolts. Used to be a popular mod a couple of years ago, but drilling them out compromises the structural integrity of the bolt and that's not something you want to break when you try to take it out later.
Yea drilling don't sound too appealing. I found some "upgraded bolts" on ebay for $25. I called the dealer and the 6.4 bolts are $26 a piece!
I would think it would be a good idea if you have a HOT tune.
