Typical aftermarket exhaust manifold bolts are much shorter than stock which after numerous heat cycles can cause them to fatigue and start to stretch, leading to exhaust leaks and possible breakage after repeated re-torques. The finish and coating on most of these bolts can also lead to premature corrosion and zinc embrittlement. Replace damaged or corroded exhaust manifold bolts with BD Diesel class 10.9 bolts and spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement. Order the kit recommended for your vehicle and engine application. BD Diesel exhaust manifold bolt and spacer kit #1041483 details: * Exhaust spacers ensure fastener operates in elastic stretch without fracture or permanent yield * Class 10.9 hardware * Non-zinc plated fasteners prevent zinc embrittlement * Includes 16 exhaust spacers (18mm) * Includes 16 flange head exhaust bolts (M8x1.25 – 40mm 10.9)

We have put together these Summit Racing™ exhaust gasket and bolts Pro Packs to ensure a leakproof seal for your headers. They feature Fel-Pro Performance exhaust header gaskets made from high-temperature, high-density fiber material around a perforated steel core for durability and heat resistance. To provide a tight seal, we include Stage 8's Grade 8 locking header bolts. They use a patented system that consists of a grooved hex head bolt, 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.

Cometic MLS head gaskets are constructed from multiple layers of stainless steel for strength and contain load-controlled embossments that conform load distribution across the sealing area. This creates an exceptional seal by requiring less clamp load—resulting in less bore distortion. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing. MLS head gaskets are available for most aftermarket cylinder heads; as with all of Cometic's MLS head gaskets, no sealants or re-torque is required.

Fel-Pro's PermaDryPlus valve cover gaskets feature precision edge-molded silicone rubber, which resists high heat and delivers reliable sealing on irregular surfaces. This silicone rubber is wrapped around a rigid carrier that adds strength to the gasket to resist being sucked in under high vacuum or blown out when under pressure. At the same time, it also prevents over-tightening of the mounting bolts. Note, however, that these gaskets are not intended for race applications.

Simple logic says that one of the best ways to avoid oil pan leaks is to make the pan gasket one piece. That's the philosophy behind Milodon's one-piece pan gaskets. They end leaks at the corners, where multi-piece gaskets often fall down on the job. Molded in one continuous piece of rubber, with steel inserts around each bolt hole, the bolts can be securely tightened but not over-tightened. Because of this construction, these gaskets are reusable.
