What material are these COMP Cams valves made from?

These valves are constructed from a 21-4N forged high-strength steel alloy. This material is chosen for its ability to handle the demands of performance and competition engines while maintaining durability.

Do I need to use lash caps with these valves?

No, you do not need to use separate lash caps. The valve tips are hardened to a minimum of 50 HRc, which is sufficient to prevent wear without the need for an additional lash cap.

What is the benefit of the swirl-polished fillets?

The swirl-polished fillets under the valve head help to increase airflow into the combustion chamber. This design also reduces stress concentration, making the valves more resistant to cracking and failure.

Product Details

If you're rebuilding a performance Big Block Chevrolet engine, getting the intake and exhaust valves right is key to unlocking power and ensuring reliability. These COMP Cams Sportsman Stainless Steel Exhaust Valves are built for street and competition use, offering a solid upgrade over stock components. They feature a 1.880-inch head diameter and a 5.454-inch length, designed to fit a wide range of Chevrolet and other vehicles from the mid-60s through the early 2000s, including popular models like the Chevelle, Camaro, and C10 pickups.

These valves are made from a strong 21-4N forged steel alloy, chosen for its high performance and durability. The tips are hardened to 50 HRc, meaning they don't require a separate lash cap, which simplifies installation. COMP Cams also applied a hard chrome plating to the 11/32-inch stems, along with a special surfacing that helps retain oil. To help the engine breathe better, these valves have a high-flow fillet relief under the head, and the swirl-polished finish further improves airflow while also making them more resistant to cracking.
