Mr. Gasket Header Bolt Set - Allen Head 3/8-16 x 3/4 Inch - 916 pressure-plates 5 V8 1962 - 1971Overview: 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. Sold as a set of 12 Fits: AMC 290 401 Chevrolet Small Block 262 400
