About this part

Product Details

If you're rebuilding the top end of your Chevy Big Block engine, especially for racing applications under 8000 RPM, these Manley Race Master intake valves are a solid option. They're built from stainless steel, which gives them good durability for the heat and stress these engines see. The set includes eight intake valves, each with a 2.190-inch head diameter and a 5.344-inch overall length.

Manley puts a lot of care into these valves. They've got chrome stems and hard tips to help them last longer and resist wear, even with frequent use. The under-head areas are swirl polished, and the combustion faces are machined to help air move smoothly into the cylinder, which can make a difference in how efficiently your engine burns fuel. You can choose between the Race Master straight stem design or the Race Flo shape, depending on what your specific engine build needs.

These are particularly recommended for alcohol-fueled engines, especially for the exhaust side, though these are intake valves. They're designed to handle the demands of bracket, drag, and oval track racing, so you can be confident in their performance when you're pushing your engine hard.
