This Patriot Seal-4-Good flange gasket is built from multi-layered aluminum that conforms to the flange to make a lasting exhaust seal. It is sized for big-block Chevy 396, 427, and 454 engines with square exhaust ports.
The soft aluminum construction fills minor imperfections in the mating surface, making it a reliable seal for headers that get removed frequently.
