Ferrea Chevrolet SB 1.6in 5/16in 5.06in 20 Deg Flo Rad Grv +.150 6000 Series Exhaust Valve- Set of 8

If you're rebuilding the top end of your Chevrolet Small Block engine, getting the right valves is crucial for performance and reliability. These Ferrea 6000 Series exhaust valves are built to handle the demands of a performance engine, ensuring your intake and exhaust ports seal properly for optimal power delivery.

Ferrea uses high-quality steel for these valves, heat-treated to withstand the high temperatures and pressures found in performance V8s. The 1.6-inch head diameter and 5/16-inch stem are standard sizes for many popular Chevy SB applications, and the 20-degree back angle on the head helps improve flow. This particular set is also +.150 inches longer than stock, which is important to consider if you're using specific cylinder heads or valvetrain components that require this length for proper geometry.

This set includes eight valves, enough for a complete V8 engine. When installing, pay close attention to valve guide clearance and ensure your valve springs are matched to the valve weight and intended RPM range for best results.
