Exhaust manifold bolts
Fit fine, worked great

LS motor update.
header bolts fit well. Made clearing pipes very easy. Could not use washers because of Bolt length being too short for this application.

Manifold bolts
These bolts will work with the factory manifolds on a 2004 2500 hd with a 6.0 gas burner, little bit of a pain to start but they work great!
