1980 Honda CB650 · Exhaust Port Seals & Studs Buying guide
The gasket and stud packages have different contents. Compare the existing exhaust attachment and condition of the cylinder-head fittings before deciding whether the job requires seals alone or new mounting hardware.

The single port-gasket item supplies one piece, while the larger pack supplies ten under the same stated reference family. Confirm the port application and count the joints being serviced. The larger pack is a quantity choice, not a different sealing location.
Eight studs and eight flange nuts are listed in the hardware set. Assess the retained studs and head threads before planning removal and replacement. Use the proper service procedure rather than assuming a new set repairs damage to the head’s threaded holes.
Honda’s Common Service Manual calls for a new exhaust-pipe gasket whenever the pipe is removed from the engine. Include a replacement for each opened port connection and use the model-specific manual for assembly and tightening.
No. Inspect the head threads before installing replacement studs. The stud supplier calls for proper extraction methods for seized hardware rather than forcing it in the aluminum head, followed by the specified installation depth and even flange-nut tightening. Resolve damaged threads before relying on new hardware.
Compare the engine-port attachment and gasket specification with the exhaust manufacturer’s requirements. The motorcycle application alone does not verify every altered pipe flange or mounting arrangement.
