When installing headers you will need header bolts, factory exhaust manifold bolts wont work. These Mr. Gasket Header Bolts are Grade 5 for strength, black oxide coated, and have a hex head that is ideal for use where space is minimal - your typical header flanges. Ever had a set of headers where a socket just seemed it wouldnt fit? These bolts also have a socket head or Allen key drive in the center for just that problem.
