Default Bolts on headers
I'm installing LT's and I need to know how much torque you tighten the bolts? Also I got the headers from a friend and he lost one of the bolts. Can I you use one of the manifold bolts?

Yes you can use the manifold bolts. I don't remember the torque specs though sorry.

The specs are probably 20-25 lb ft. I just put them pretty snug and checked them a week later.

You need to look the torque requirements up to verify. If I remember correct it is 18 ft. lbs.
