Ferrea Nissan VR38DETT 32.2mm 5.97mm 92mm 24 Deg Taper Flo Stk Super Alloy Exhaust Valve - Set of 12

If you're rebuilding the top end of a Nissan VR38DETT engine, especially for a high-performance application, you'll want to pay close attention to the exhaust valves. These Ferrea Super Alloy Exhaust Valves are built to handle the intense heat and pressure these engines can generate. They're designed with a 32.2mm head diameter and a 5.97mm stem, fitting right into the stock valve guides and seats.

What sets these valves apart is the super alloy material they're made from. This isn't your average steel; it's a specialized metal designed to resist extreme temperatures and resist wear under heavy load. The 24-degree taper on the valve face helps create a solid seal against the valve seat, which is crucial for maintaining compression and preventing exhaust gas leakage, especially when you're pushing the engine hard. Each valve measures 92mm in overall length, matching the stock dimensions for a straightforward installation into your cylinder head.

This set includes 12 valves, enough for a complete engine. When you're building an engine that needs to perform reliably under demanding conditions, using well-built components like these Ferrea valves is a smart move. They're a key part of ensuring your engine breathes efficiently and stays sealed under boost and high RPMs.
