      Description

      Advanced Multi-Layer Composite Construction. The Ultra-Seal Header Install Kit; Oval Ports features a specialized high-density fiber core laminated to a graphite or wire-mesh reinforcement, depending on the specific application, to prevent blowouts under high back-pressure. Unlike standard paper or thin metal gaskets, the Ultra-Seal Header Install Kit; Oval Ports is designed to compress and conform to minor flange warping or surface pits commonly found on aged Small Block V8 components. This resilient material technology allows the gaskets to maintain their torque over time, reducing the need for constant re-tightening and ensuring a long-lasting, maintenance-free seal for your Corvette.

      Optimized Oval Port Design for Maximum Airflow. Specifically tailored for the popular oval-port head configurations found across decades of Chevy production, the Ultra-Seal Header Install Kit; Oval Ports ensures a completely unobstructed exit for exhaust gases. The Ultra-Seal Header Install Kit; Oval Ports is precision-trimmed to match the port window exactly, eliminating any overhang that could create turbulence or restrictive heat spots at the exhaust exit. This meticulous design makes the kit a perfect match for 1955-1991 Small Block V8 Corvette models, whether you are running factory-style manifolds or upgraded long-tube headers on your C1 through C4 project.

      Installation. Putting this Ultra-Seal Header Install Kit; Oval Ports on your Small Block V8 Corvette C1, C2, C3 & C4 takes 2 hours to install.

      Warranty. There is a limited lifetime warranty on this product.

      Application. The Ultra-Seal Header Install Kit; Oval Ports fits 1955-1991 Small Block V8 Corvette C1, C2, C3 & C4 models.
