1970 Honda SL350K0 Intake & Exhaust Valves

Head work on an SL350K0 needs the intake and exhaust positions identified before parts are counted. This selection offers separate replacement valves; choose by valve function and reference, then let the head inspection determine the rest of the repair.

1970 Honda SL350K0 · Intake & Exhaust Valves Buying guide

Select the correct valve for each head position

The intake valve uses reference 14711-286-030. The exhaust valve uses references 14721-286-305 and 14721-286-020. These are separate items with different roles, not an interchangeable valve pair.

Make a position-by-position parts list

The intake valve is sold individually. Keep its quantity separate from the exhaust-valve order and from any other head-service items. Label removed valves by position so the rebuilder’s findings translate into the right parts rather than an assumed full-engine set.

Let the head condition guide the work

A valve’s replacement reference is useful identification, but it cannot tell you whether the seat or guide also needs attention. Have those surfaces assessed before assembly. Use the applicable SL350 service information for inspection limits and the rebuilder’s final machining requirements.

Ordering questions

Are intake and exhaust valves bought as a matched pair?

They are separate product entries with different replacement references. The intake is explicitly sold individually. Order the positions your head inspection identifies and confirm the exhaust package quantity before treating any order as a full set.

Should I order valves before the cylinder head is inspected?

An inspection can establish whether replacement valves alone are appropriate or whether guide and seat work is also needed. Ask the rebuilder for a position-specific parts list before committing to quantities.

Which references distinguish the two choices?

Use 14711-286-030 for the intake entry and 14721-286-305 or 14721-286-020 for the exhaust entry. Compare these with the fitted parts and exact application; the shared engine family is not sufficient identification by itself.

Not sure which part you need?

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