The Exhaust Gasket 302-351W with GT40 Heads by Mr. Gasket is a precision-engineered exhaust manifold gasket designed for small-block Ford engine builders and enthusiasts running aftermarket GT40 cylinder heads. This gasket seals the critical interface between your exhaust manifolds and the GT40 head ports, preventing exhaust leaks that compromise performance, fuel economy, and longevity.
Manufactured to match the unique port geometry of GT40 heads paired with 302 or 351W block applications, this gasket ensures a proper seal without gaps or compression loss. The gasket material resists high exhaust temperatures and thermal cycling that cause standard gaskets to fail prematurely. Precision die-cutting guarantees dimensional accuracy across all mounting holes and port openings, making installation straightforward.
Serious Ford builders and restorers trust Mr. Gasket for OEM-quality sealing solutions that outlast inferior alternatives. This gasket is essential when upgrading to GT40 heads on small-block Ford engines—mismatched gaskets lead to leaking, rough idle, and diagnostic headaches. Proper installation requires adherence to the correct torque sequence for optimal performance.
