About this part

Product Details

These Manley Race Flo intake valves are built with a 2.120-inch head diameter, specifically designed for Chevrolet LT1 6.2L engines. They are constructed from high-quality stainless steel, a material chosen for its strength and resistance to the high temperatures found in performance engines. The chrome stems and hard tips add extra durability, helping these valves stand up to wear and tear over time, especially in engines that see a lot of use or operate at higher RPMs.

You'll notice the swirl-polished under-head areas and fully machined combustion faces. This design work helps improve airflow into the cylinder, which can contribute to better combustion efficiency. These are the Race Flo shape, which is a specific design choice for certain racing engine configurations. Manley also recommends these valves for use in alcohol-fueled engines, indicating their robust construction and ability to handle demanding conditions.

This set includes eight intake valves, enough for a complete engine rebuild or upgrade. If you're working on a performance LT1 6.2L and need reliable valvetrain components, these Manley valves are a solid option.
