Ferrea Honda D16Z6/Y5/Y7/Y8 27mm 5.46mm 22 Deg Flo Rad Grv +1mm 6000 Series Exh Valve - Set of 8

These Ferrea 6000 Series exhaust valves feature a 27mm head diameter and a 5.46mm stem, designed for specific Honda D16 engine applications. The valves are built with a +1mm oversized stem, which can be beneficial for rebuilding or modifying engines where valve guides might have been reamed or worn. This specific design choice helps ensure a proper fit and seal within the cylinder head.

Constructed from Ferrea's 6000 Series alloy, these valves are well-built to handle the heat and stress of exhaust gases. The 'Flo Rad Grv' refers to a groove on the valve stem that can aid in lubrication and reduce friction, contributing to smoother operation and potentially longer valve life. The 22-degree back angle on the valve head is a common design feature that helps improve flow characteristics as the valve opens and closes within the combustion chamber.

This set includes eight exhaust valves, making it a complete solution for a typical D16 cylinder head. If you're rebuilding the top end of your Honda D16Z6, D16Y5, D16Y7, or D16Y8 engine, these valves offer a solid option for ensuring reliable performance and proper sealing.
