11/32 Exhaust Valves - 1.600

The DEL WEST 11/32 Exhaust Valves with 1.600-inch head diameter are purpose-built performance components for small-block Chevy and Ford engines requiring titanium construction and precision engineering. This set of eight exhaust valves delivers the material properties and dimensional accuracy required for high-RPM, high-heat engine applications where standard steel valves reach their thermal and mechanical limits.

Each valve features an 11/32-inch valve stem and measures 5.140 inches in length, enabling direct compatibility with standard small-block Chevy and Ford cylinder heads without modification. Titanium construction offers a critical advantage: substantially higher melting point than steel, reduced weight, and superior strength-to-weight ratio. These properties allow sustained operation at elevated combustion temperatures and engine speeds while minimizing inertial loads on valve train components—particularly important in racing engines, forced-induction applications, and sustained high-load scenarios where exhaust valve durability becomes a limiting factor.

This valve set is engineered for engine builders, performance shops, and serious enthusiasts rebuilding small-block Chevy or Ford engines destined for competition, street performance, or extended high-RPM service. Titanium exhaust valves are essential when OEM steel valves cannot withstand the thermal stress of nitrous, supercharger, or turbocharger applications, or when chronic valve recession or recession wear becomes a recurring problem in naturally aspirated engines run at continuous high RPM.
