Brian Crower 26mm Exhaust Valves for Honda D16Y8/D16Z6

Brian Crower 26mm Exhaust Valves for Honda D16Y8/D16Z6

The Brian Crower BC3071 exhaust valves are replacement exhaust valves for Honda D series single overhead cam VTEC cylinder heads used on D16Z6 and D16Y8 applications. In the valvetrain, the exhaust valve seals the combustion chamber during compression and power strokes, then opens to discharge spent gases into the exhaust port. Correct valve head diameter, stem diameter, overall length, and keeper groove geometry are required to maintain installed height, spring engagement, and proper sealing at the seat.

BC3071 is configured as a standard size exhaust valve for these heads, retaining factory style dimensions rather than increasing head diameter. This makes it a common choice when rebuilding a worn cylinder head, replacing damaged valves, or refreshing a head during camshaft and spring service while keeping standard seat geometry.

Key Features

• Manufacturer part number: BC3071
• Valve type: Exhaust
• Valve head diameter: 26 mm
• Stem diameter: 5.45 mm
• Overall length: 116.0 mm
• Material: Stainless steel
• Valve face profile: Dished

Selection considerations: Because these are standard diameter valves, they are intended to work with standard exhaust valve seats and do not inherently change port throat size or seat insert requirements. Any cylinder head rebuild should confirm valve to guide clearance, seat condition, and concentricity, followed by a valve job as needed to restore sealing. Always verify installed height and retainer keeper engagement during assembly, particularly if the head is being paired with non stock springs or retainers.
