Manley Chevy LS-3/L-99 (L-92 Head) Small Block Race Flo Intake Valves (Set of 8)

These Manley Race Flo intake valves are made from NK-842 stainless steel, a material chosen for its strength and resistance to heat, making them a solid choice for performance builds. They feature a 2.165-inch head diameter and a 0.3133-inch stem diameter, with an overall length of 4.900 inches. The under-head areas are swirl polished to help smooth airflow into the combustion chamber, and the combustion faces are fully machined for better efficiency.

Designed for engines operating under 8000 RPM, these valves are well-built and ready for demanding use in drag, oval track, or bracket racing applications. The chrome stems and hard tips add to their longevity and wear resistance, which is important for consistent performance over time. These are specifically the 'Race Flo' shape, which is a particular design choice for certain engine builds.

This set includes eight intake valves, fitting a range of popular GM vehicles like the Cadillac Escalade and GMC Yukon from the 2007-2008 model years, as well as the Hummer H2 in 2008. If you're rebuilding the top end of one of these LS-based engines, these valves are a strong option to consider for improved airflow and durability.
