These valves are 1MM larger than stock (stock valves are 31.50MM), and great for ported street heads. These Inconel valves are lighter than the stock steel valves and are extremely heat resistant; These are a special high nickel-based alloy that goes through a unique heat-treatment process, which yields extreme heat resistance and enormous tensile strength properties resulting in better valvetrain stability. A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market These valves will work with the stock seats once a performance valve job has been performed. It is highly recommended to unshroud the valve with a bowl and chamber port work when using oversized valves.
