1970 Honda CB350K2 · Valves & Valve Guides Buying guide

Choose head parts by position and measured wear

Before ordering valves, have the cylinder head assessed as an assembly. Worn guides, damaged seats and worn valve stems need different parts and preparation, even when the engine presents the same compression complaint.

Keep intake and exhaust choices separate

The intake replacement references 14711-286-030; the exhaust replacement references 14721-286-305 and 14721-286-020. Match the removed part and its position, then have seat condition and fit checked. A new valve alone does not establish that the head is ready for assembly.

Plan guide replacement with the machinist

The standard-size Kibblewhite guides use C63000 nickel-aluminum bronze and are sold individually. Their design does not use separate OEM-style guide clips. Discuss the guide, head bore and finish work together; the linked exhaust guide is the corresponding exhaust-side choice.

Common buying questions

Are intake and exhaust guides interchangeable?

Select the guide intended for each position. Separate Kibblewhite intake and exhaust products are offered, so identify the head location rather than ordering both from a single guide listing.

Are the Kibblewhite guides sold as a full head set?

They are sold individually. Count the intake and exhaust positions your rebuild actually needs, then order the corresponding guide quantities after the cylinder head has been inspected.

Should I order standard-size guides before the head is measured?

Have the machine shop assess the existing guide bores first. Standard size is a specific replacement choice; the correct fit and finishing work depend on the condition of the head.

Not sure which part you need?

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