SBC R/M 2.055in Intake Valves

The MANLEY SBC R/M 2.055in Intake Valves are a specialized solution for small-block Chevrolet engine builders looking to enhance intake flow efficiency. These valves are crucial for performance rebuilds, whether for street-strip hybrids, competition engines, or restoring classic muscle cars with modern reliability.

Featuring a 2.055-inch head diameter, these valves optimize intake port efficiency in SBC platforms without extensive modifications. Constructed from stainless steel, they offer superior corrosion resistance and thermal stability, essential for high-RPM operation. The design also ensures precise seating geometry, which is vital for effective combustion chamber scavenging.

Ideal for engine builders, performance shops, and dedicated enthusiasts, this eight-valve set fits specific small-block Chevrolet applications, including 283, 305, 327, 350, and 400 engines. The lightweight design minimizes valve train inertia, allowing for higher RPM limits and more aggressive cam profiles without risking valve float or spring surge.
