Manley Big Block Chevy 1.880 Dia Race Master Intake Valves (Set of 8)

Starting with a 1.880 inch diameter, these Manley Race Master intake valves are built for serious performance in Big Block Chevy engines. They are constructed from high-quality stainless steel, chosen for its ability to stand up to the heat and stress of racing applications, especially in engines running up to 8000 RPM. This set includes eight intake valves, ready to be installed in your performance build.

You'll notice the chrome stems and hard tips on these valves, which are added to increase their lifespan and resist wear. The under-head areas are swirl polished to help smooth airflow into the combustion chamber, and the combustion faces are fully machined. This attention to detail in machining and polishing helps optimize how air and fuel mix, contributing to better combustion efficiency. These are the straight stem 'Race Master' style, designed to fit specific racing engine requirements.

Manley recommends these valves for alcohol-fueled engines, particularly for exhaust applications, highlighting their reliability under demanding conditions. If you're rebuilding the top end of your Big Block Chevy for bracket, drag, or oval track racing, these valves are a solid option to consider for improved performance and durability.
