I hope the other bolts don't break if they have to be removed to replace the broken one (some of them look the same - rusted)

Another concern if it is leaking would be gases entering cabin when car is idling.
Looks like a good time to add some long tube headers.

It's rusted badly, so it shouldn't be from the C6, unless you drive it in the snow.salt, etc.
It could have been picked up from the road, and deposited itself on the spring. It fell out on the garage floor. If your bolts are intact on the front deflector, then it's a crapshoot to where and if it belongs on the C6.

Why is chevy using grade 10 bolts on a manifold?
I get it on other pieces such as suspension/cradle and such, but it seems to me that these bolts would be stronger than the head and likely not a good choice. Someone school me on material science.

Here is something that at least explains 10.9 bolts, tensile strength, ductility, and fatigue failures to some degree. Starts on page 1 & continued on page 6.
Keep in mind this is kind of a harsh environment for a bolt. Lots of high heat/cool cycles that are always working against it.

Also spoke to my buddy there that's the shop foreman/lead master tech. Same story.
I've seen them snap off on other makes (ford, Chrysler) quite frequently too. But those were also corroded from the rust belt we live in, and those manifolds tended to either be cracked or warped too.
