Ferrea Chevy/Chry/Ford SB 1.625in 11/32 5.06in 24 Deg S-Flo Rad Grv +.150 Hollow Exh Valve- Set of 8

These Ferrea exhaust valves feature a 1.625-inch head diameter and a 24-degree swirl-flow radius groove, designed to improve airflow into the cylinder. The 11/32-inch stem and 5.06-inch overall length are common dimensions for many Chevy, Chrysler, and Ford small-block V8 engines, making them a solid choice for performance builds or replacements.

Constructed from high-strength, heat-resistant alloy, these valves are built to withstand the demanding conditions inside an engine. The hollow stem design helps reduce overall valve weight, which can lead to improved valve train stability at higher RPMs and potentially faster engine response. The +.150 inch oversize on the stem diameter indicates these are intended for applications where the valve guides may have been reamed or modified to accommodate them, often seen in performance engine rebuilding.

This set includes eight valves, enough for a typical V8 engine. When rebuilding or upgrading your engine's top end, using well-made valves like these from Ferrea can make a notable difference in performance and reliability.
