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, black oxide coated, and have a compact 7/16" hex head that is ideal for use where space is minimal - your typical header flanges. This 100 piece count set is designed for shops, but its also handy if you have several cars with headers or just want to have a stock on hand. Fits: AMC 290-401 Chevrolet Small Block 262-400 Chevrolet Big Block 396-454 Chrysler 383-440 except Hemi Ford 221-351W Oldsmobile 330-455 Pontiac 326-455
