1982 Honda CB750C · Headpipe Sealing Service Buying guide

Match the gasket to the cylinder-head joint

The featured gasket is sold each and includes reference 18291-MM5-860. A related individual gasket is an alternative for that joint. The manifold stud is separate fastening hardware with an 8 × 55mm specification.

Count seals for the actual dismantling

One gasket is supplied per product. Count the headpipe joints included in the repair and check whether a larger engine gasket package already supplies them. The related gasket alternative should be compared as another product choice for the same joint, not an additional stacked seal.

Inspect the mounting before reassembly

The related 8 × 55mm manifold stud replaces 90035-425-000. Compare the retained fastener and receiving threads before ordering. A changed exhaust may have different mounting requirements elsewhere, so follow the service guidance for the actual connection being rebuilt.

Headpipe Sealing Service questions

Does one gasket purchase cover all four ports?

No, it is sold individually. Count the ports included in the work and any suitable exhaust gaskets already supplied in a larger engine package before choosing quantity.

Should I buy both gasket alternatives for one joint?

They are alternative individual products sharing a headpipe-gasket reference. Compare their details with the joint being serviced and choose the appropriate replacement rather than assuming two seals are required together.

What should be checked with an aftermarket exhaust?

Compare its cylinder-head connection, retaining pieces and stud requirements. Identify other changed joints separately, since their seals and hardware may differ from the original arrangement.
