18 Deg Chevy Int Gasket HIGH PORT .045in THICK

The 18 Deg Chevy Int Gasket HIGH PORT .045in THICK from FEL-PRO is designed for serious small-block and big-block Chevy engine builders and mechanics who require precise port matching and reliable sealing. This high-port intake gasket is specifically engineered for modified Chevy engines where cylinder head porting and high-flow intake manifolds necessitate accurate gasket placement.

With an 18-degree port orientation, this gasket matches the intake manifold flange angle on select Chevy engine configurations, optimizing flow characteristics and minimizing vacuum leaks. The .045-inch thickness offers optimal compression and sealing compliance, ensuring durability and maintaining port velocity. The high-port design accommodates ported cylinder heads with raised intake ports, allowing for unobstructed fuel and air mixture flow.

Engine builders working on Chevy stroker builds, crate engine installations, or cylinder head upgrades will find this gasket essential for maintaining effective combustion chamber sealing. Its design is particularly beneficial for performance builds that demand high airflow and reliability under various operating conditions.
