I'll get around to making sure the threads are good some time.
You're lucky Josh, I've seen headers leak that were perfectly torqued, with clean surfaces and new gaskets...and all bolts installed. Granted the GM steel gaskets are forgiving, but loose or missing hardware on the header flange usually isn't...

Soaking it wont do anything. The bolts are already snapped off before you even touch them.

I think it's just completely dependent on how many hot/cold cycles the bolt has gone thru (i.e. the age/mileage)

I think that is a good guess by far... Brand new trucks have had them break, along with old ones. It is the nature of the beast in this case.. Some will some won't...

Yah the trick is lock washers with anti seize. The main reason it does this is the difference in the metals, aluminum is extremely corrosive..
