These kits from Mr. Gasket are complete header gasket and fastener installation kits. Mr. Gasket was the first to incorporate slotted mounting bolt holes at the ends of each exhaust gasket. This allows the gasket to be installed without removing the header flange entirely from the cylinder head, making installation faster and easier. Premium Ultra-Seal exhaust and collector gaskets provide excellent heat resistance, and conform to and seal minor surface irregularities. Mr. Gasket header and collector bolts provide the proper clamp-load to seal flange mating surfaces. All gaskets and fasteners necessary for header installation are included.

Summit Racing™ split lock bolt kits put a new twist on the theory of mechanical locking fasteners. These innovative bolts use a locking set pin built into the bolt itself—and when tightened, the set pin expands the bolt threads against the thread wall. This, in turn, provides a locking system without having to use any additional wires, locking compounds, or lock washers. To remove the split lock bolts, simply loosen the set pin and back out the fastener. They are available in a variety of thread sizes, for engine applications from the 1950s and up.

Stage 8's Grade 8 locking header fasteners use a patented system that consists of a grooved hex-head bolt or nut, a retainer, and a snap clip. The retainer fits over the bolt head and locks the bolt against the header tube, and the snap clip holds the retainer in place. Once Stage 8 header fasteners are tightened down, they won't back out, eliminating leakage and blown header gaskets from loose bolts.
