Header bolts

[Jimmyvonviggle]

While under the car I noticed what appears to be bolts missing from my headers, as well as some nuts. How many bolts or studs is suppose to hold them on and what are their dimensions?

Only two per outlet, diagonal from each other

The studs are 7mm. If you find you have some studs that have snapped off then this thread may be helpful for removing the manifold, replacing the studs, and reinstalling.

I'm pretty sure I've got an exhaust leak on my car due to a couple of broken studs. I'd prefer not to mess with the manfolds more than once so I'll probably wait to deal with it until I go to an aftermarket header/exhaust setup. (Probably DPI's Spec 1 w/ new stainless studs)
