Construction & Design

These header gaskets are constructed from Cometic’s proprietary HT compressed material, which is engineered to endure the intense heat and pressure generated by the 5.7L Hemi engine’s exhaust gases. The .060-inch thickness balances durability with the necessary flexibility to create a tight seal without damaging header flanges. The round port design with a 1.8-inch diameter ensures a perfect match to factory header ports, minimizing exhaust turbulence and promoting efficient flow.

Cometic’s commitment to quality is evident in their manufacturing process, which includes rigorous material selection and precision cutting to maintain consistent dimensions and performance. This results in a gasket that not only fits perfectly but also maintains its integrity over extended use.

Installation & Fitment

Installation of the Cometic HT Header Gaskets is straightforward for anyone familiar with exhaust system maintenance. These gaskets are designed as direct replacements for factory header gaskets on compatible 5.7L Hemi vehicles, requiring no modifications to the headers or cylinder heads. Proper torque specifications should be followed to ensure a secure seal and prevent exhaust leaks.
