Ferrea Chevrolet SB 1.6in 11/32in 5.56in +.600 Super Alloy Exh Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Chevrolet Small Block engine, especially if you're pushing the limits with higher lift cams or boosted applications, you'll want to consider these Ferrea exhaust valves. They're built from a super alloy that can handle the intense heat and stress found in performance V8s. The 1.6-inch head diameter and 11/32-inch stem are standard for many SB applications, but the +.600 inch length means these are designed for setups where you might have modified cylinder heads or need extra clearance for valve springs and retainers.

Ferrea is known for making well-built valvetrain components, and these valves are no exception. The super alloy material is chosen for its strength and resistance to high temperatures, which is crucial for exhaust valves that see the hottest gases in the combustion chamber. This particular valve is 5.56 inches long overall, with the +.600 measurement indicating it's longer than a stock valve to accommodate specific build requirements. It's a single valve, so you'll need to order the correct quantity for all cylinders.
