The Patriot Exhaust 66036 Seal-4-Good exhaust header gaskets are designed to provide a dependable seal between the cylinder heads and headers on Mopar B-Series and RB-Series engines. These replacement gaskets feature a rectangular port design engineered for compatible big-block Mopar applications, helping minimize exhaust leaks and maintain proper header performance.
Constructed from multi-layered aluminum, the 66036 gasket set combines strength, conformability, and heat resistance for demanding exhaust-system environments. The layered construction helps accommodate minor surface irregularities while supporting a reliable seal during repeated heat cycles. Each gasket is formed with a 1.800 x 1.500-inch rectangular port opening to match compatible header and cylinder-head configurations.
This Patriot Exhaust Seal-4-Good set includes a pair of exhaust header or manifold gaskets, making it suitable for servicing both sides of a V-type engine. Verify header design, cylinder-head configuration, and port shape before installation to ensure proper fitment. The gaskets are intended for automotive exhaust applications and provide a practical replacement solution for worn, damaged, or leaking header seals.
