Jim ....
1.) Studs give better clamping force than a bolt.
2.) You are working with aluminum, which is a "soft material". It is very easy to pull threads/cross thread when inserting a bolt and especially when you overtighten it.
There's my nickel's worth.
You can always back studs out and replace them...when you cross thread a bolt you can screw up the soft aluminum...then ya gotta retap, cuss swear, bitch and holler.....
