Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.
