Ferrea Chevrolet SB 1.6in 7mm 5.16in 0.29in 12 Deg +.200 Super Alloy Exhaust Valve - Set of 8

This set includes eight Ferrea Super Alloy exhaust valves, each measuring 1.6 inches in diameter. These valves are specifically made for Chevrolet Small Block engines and are designed for performance applications where durability and heat resistance are critical.

Crafted from a high-performance super alloy, these valves are built to withstand the extreme temperatures and pressures found in performance engine builds. The 7mm stems offer a good balance of strength and weight, while the 5.16-inch overall length and 0.29-inch margin provide the necessary dimensions for proper seating and sealing. The 12-degree seat angle is a common specification for many performance heads, and the +.200 inch sizing indicates they are intended for engines that have been machined for larger valves or require specific piston-to-valve clearance adjustments.

When rebuilding or upgrading a Chevrolet Small Block engine, especially for racing or high-performance street use, selecting valves that can handle the increased stress is important. These Ferrea valves are a solid option for those looking for robust components for their engine's top end.
