1977 Honda CB550K · Valvetrain Parts Buying guide

Identify the valve position and seal quantity

Intake and exhaust valves use different references. Stem seals are another component, with individual and packaged choices in the current listings; compare both product type and sale quantity before completing the cylinder-head order.

Keep intake and exhaust references separate

The featured intake valve references 14711-107-020, while the exhaust valve lists 14721-323-005 among its replacement references. Compare the required valve position with the appropriate product. Similar-looking valve photos are not a substitute for identifying which valve the cylinder-head repair actually needs.

Compare the sale quantity of the seal products

The standard replacement seal description says sold each. The Kibblewhite listing describes eight 100% Viton seals in one set, with the same 12209-333-005 reference. Choose according to the required seals and the package offered; the sale count does not assess the condition of the existing head.

Common ordering questions

Can an intake valve be chosen as an exhaust replacement?

The featured products are separately described for intake and exhaust positions and use different reference information. Identify the required valve before ordering and compare its specified replacement, rather than treating the two listings as equivalent valves.

How many standard stem seals come with one purchase?

The current description says the standard replacement seal is sold each. Order the quantity required for the work specified on the fitted head; the separate Kibblewhite product is described as an eight-piece set.

What material is stated for the Kibblewhite seals?

The description states 100% Viton and eight seals per set. Those are product specifications, distinct from the individually sold standard seal. Compare the selected seal and the head-work requirements before deciding which package to purchase.
