Ferrea Chevy/Chry/Ford SB 2.2in 5/16in 5.285in 0.29in 12 Deg Titanium Comp Intake Valve - Set of 8

This set includes eight Ferrea Competition Series titanium intake valves, designed for Chevy, Chrysler, and Ford small-block engines. Each valve features a 2.2-inch diameter face and a 5/16-inch stem, with a length of 5.285 inches. The 12-degree seat angle and 0.29-inch margin are critical for proper sealing and airflow in high-performance cylinder heads.

Titanium construction is key here. It's significantly lighter than steel, which reduces valve float at high RPMs and puts less stress on the valve springs and valvetrain. This allows for more aggressive camshaft profiles and higher engine speeds. The material also offers good resistance to heat and wear, making these valves a solid choice for builds where durability and performance are paramount. Ferrea is well-known for making strong valvetrain components, and these valves are built to handle the demands of competition engines.

When rebuilding or upgrading your engine's top end, using high-quality valves like these can make a notable difference in performance and reliability. Ensure your cylinder heads are machined to accept the 12-degree seat angle and the specific margin dimension for optimal performance. These valves are typically used in performance builds where every ounce of weight savings and every bit of airflow matters.
