Description
If you’re building or rebuilding a high-performance small block Chevy, valve choice directly impacts combustion efficiency, cylinder head flow, and overall engine reliability under sustained RPM. Manley’s Race Flo exhaust valves are engineered with a larger 1.560-inch head diameter to maximize flow characteristics while the stainless steel construction resists thermal fatigue and corrosion—critical when running lean air-fuel ratios or aggressive ignition timing. This is a complete set of eight valves, ready to drop into your SBC cylinder head.
