Header Gasket Set - SBM

The Header Gasket Set - SBM by FLOWTECH is a precision-engineered exhaust manifold gasket pair designed for Small Block Mopar engines where reliability and heat resistance are non-negotiable. Built for enthusiasts and mechanics who understand that a quality gasket prevents exhaust leaks, maintains proper scavenging dynamics, and protects against carbon buildup at the cylinder head-to-manifold interface. This two-piece set delivers OEM-level sealing performance at a fraction of the cost, making it the smart choice for resto-mod builds, street engines, and high-output performance applications where longevity matters.

Constructed from graphite material, the Header Gasket Set - SBM resists thermal cycling and maintains a consistent seal across repeated heating and cooling cycles that destroy inferior gaskets. Each gasket features a 1.640 x 1.230 inch port opening that matches Small Block Mopar cylinder head configurations, with a 3-inch collector gasket included for proper manifold-to-primary tube transition sealing. Graphite composition allows for proper bolt torque retention without over-compression, critical for preventing header leaks that waste horsepower and create under-hood noise issues that signal problems to any discerning driver.

This set is essential for anyone rebuilding a Small Block Mopar engine or replacing worn factory manifold gaskets on street and strip machines. Installation is straightforward—clean mounting surfaces thoroughly, apply a light coat of high-temp sealant if desired, and torque fasteners in a star pattern to specification. Whether you're upgrading from failing OEM gaskets or installing a performance header system, the Header Gasket Set - SBM ensures a leak-free seal that protects your investment and keeps exhaust scavenging efficiency at peak levels for years of reliable operation.
