About this part

Product Details

Starting with a 53.5mm diameter, these Manley Race Master intake valves are built from high-quality stainless steel, specifically NK-842 for the intake side. They're designed for Ford 6.2L engines that will see serious use, like in bracket, drag, or oval track racing, especially when operating under 8000 RPM. The goal here is to get more air into your engine efficiently, which is crucial for making power.

You'll notice the chrome stems and hard tips, which are there to help these valves last longer and resist wear, even under tough conditions. Manley also swirl polishes the under-head areas and fully machines the combustion faces. This isn't just for looks; it helps smooth out airflow into the cylinder and can contribute to better combustion efficiency. If you're working on a performance Ford 6.2L and need valves that can handle the stress of racing, these are a solid option.

This set includes eight intake valves, ready to be installed in your performance engine build. They are also recommended for alcohol-fueled engines, particularly for exhaust valve applications, showing their durability in demanding environments.
