SBF 351W H/P 1.850in Exhaust Valves

The FERREA SBF 351W H/P 1.850in Exhaust Valves are precision-engineered components designed for serious Small Block Ford engine builders and performance enthusiasts. This set of eight stainless steel exhaust valves replaces factory components with OEM-plus durability and thermal stability, making them essential for high-performance builds where reliability under extreme conditions is non-negotiable. Whether you're restoring a classic 351W or building a street/strip engine, these valves deliver the consistency required for sustained power output and longevity.

Constructed from premium stainless steel, the FERREA SBF 351W H/P valves feature a 1.850-inch head diameter optimized for the 351W's cylinder head port geometry, with an 11/32-inch valve stem that maintains OEM fitment in existing guides. At 5.075 inches in length, these valves integrate seamlessly into stock or ported heads without modification, while the stainless material resists corrosion, maintains dimensional stability at elevated temperatures, and withstands the thermal cycling inherent to performance engines. The high-performance designation indicates enhanced metallurgy compared to cast iron alternatives, providing superior strength and heat rejection during sustained high-RPM operation or boost applications.

These exhaust valves are ideal for 351W engine builders tackling carbureted, fuel-injected, or even naturally aspirated forced-induction platforms seeking dependable valve durability without upgrading to exotic alloys. Installation requires only basic engine machine work—valve removal and seating—making them accessible to experienced DIY builders or professional shops. The complete eight-valve set ensures matched characteristics across all cylinders, critical for balanced combustion and consistent cylinder pressure. Verify your specific cylinder head port and valve seat dimensions before purchase; these valves are engineered for Small Block Ford applications and require proper valve seat preparation for optimal sealing.
