1972 Honda CB350K4 · Valves & Guides Buying guide

Specify each valve position before ordering

A valve, its guide and the surrounding cylinder head must be assessed together. These products offer separate intake and exhaust choices rather than a single complete head-rebuild package.

Let the head inspection determine the parts

The intake replacement references 14711-286-030; the exhaust replacement references 14721-286-305 / 14721-286-020. These are different positions. Have the valves, guides and seats assessed together, then use the findings to choose the parts and machining work required.

Account for the bronze-guide design

Kibblewhite intake and exhaust guides are standard-size C63000 nickel-aluminum bronze replacements sold individually. This design does not use separate OEM-style valve-guide clips. Ask the person carrying out the head work to confirm the required guide specification before ordering.

Buying questions

Can the intake and exhaust guides be interchanged?

Choose the guide sold for the actual position. The catalog provides separate Kibblewhite intake and exhaust products; sharing a material description does not establish that their dimensions or intended positions are interchangeable.

Do I need OEM-style guide clips with these Kibblewhite guides?

No separate OEM-style guide clips are used with the listed Kibblewhite bronze design. Follow the guide manufacturer and cylinder-head specialist’s requirements for preparation and installation.

Are the valves a matched engine set?

The intake valve is sold individually, and the exhaust product is a separate replacement. Build the quantity from the inspected positions; do not assume either product supplies all valves for the twin.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
