Blitz SS Super-Loy Intake & Exhaust Valves "LS3"

Blitz Stainless Steel Valves are designed for high RPM engines using aggressive roller cams of today. Each valve is forged from 21-4N stainless and chemically quenched for increased tensile and yield strength. The forging is machined on CNC Lathes to exacting tolerance holding concentricity to .0002". Each valve is hard chromed to prevent premature wear in the valve guide. These valves can be used in both iron and manganese guides.

Comparable to Manley Race Flo and Ferrea solid valves.
