When installing headers you will need header bolts, factory exhaust manifold bolts won't work. These Mr. Gasket Header Bolts are Grade 5 for strength and black oxide coated.
If you've ever had a set of headers where a socket just seemed it wouldn't fit these might be your answer. These bolts also have a socket head or Allen key drive in the center for just that problem.
