1980 Honda CB400TA Hawk · Valvetrain Buying guide
The factory head has four intake valves and two exhaust valves. The featured stem seal matches the intake reference; avoid treating six identical seals as a verified complete-head order.
Exhaust valveReplacement for Honda exhaust-valve reference 14721-413-000. Select by valve position rather than engine capacity alone.Voir la pièce
Intake valve-stem sealSold individually. Its 12208-413-003 reference corresponds to the four intake-seal positions in the factory head.Voir la pièce

The featured individual seal references 12208-413-003, used at four intake positions. Honda identifies the two exhaust seals separately as 12209-413-003. Build a position-by-position order; an intake-seal reference alone does not establish a replacement for all six valves.
The exhaust valve references 14721-413-000. Check the valve and its matching guide and seat together before choosing parts. The related valve-guide clip is sold separately and does not include a guide. Follow the Honda manual for the inspection limits and service method.
The original head uses four seals at the intake positions covered by reference 12208-413-003. The featured seal is sold individually; the two exhaust positions have a different factory reference.
The original head has two exhaust-valve positions, one for each cylinder, using reference 14721-413-000. Inspection determines whether one or both need replacement; keep that requirement separate from the four intake-valve positions.
Identify the replacement head’s application and valve references before ordering. The original 1980 head uses different intake and exhaust seals; if the head’s history is unknown, have the valves and guides assessed rather than selecting by frame year alone.
