Frequently Asked Questions

Which Honda engines and OEM number fit Athena head gasket 18-7000?

One Athena cylinder-head gasket cross-referenced to Honda OEM 12251-438-023 fits the listed 1979-1982 DOHC CB750 and 1980-1982 CB900 engines.

What does the DOHC CB750/CB900 cylinder-head gasket seal?

It seals combustion pressure and the oil and other passages between the cylinder block and cylinder head; it is separate from the cylinder-base and valve-cover gaskets.

What should be inspected before installing a cylinder-head gasket?

Check the cylinder deck and head for flatness, damage and residue, verify dowels and passages and follow the Honda tightening sequence and torque specifications. Do not add sealant unless the service procedure calls for it.
