BBC Rect Port Int Gasket W/O Upper Bolt Hole .125

The BBC Rect Port Int Gasket W/O Upper Bolt Hole .125 by SCE Gaskets is a precision intake manifold gasket engineered for big block Chevy engines requiring a high-performance, dependable seal. This rectangular port gasket serves serious engine builders, restoration shops, and performance enthusiasts who demand critical component reliability under sustained combustion pressures. Unlike stock gaskets prone to failure, this composite gasket is purpose-built to withstand the thermal cycling and mechanical stress inherent to modified big block platforms.

Manufactured from composite material at 0.125 inches thick, the BBC Rect Port Int Gasket W/O Upper Bolt Hole .125 features a 1.81 x 2.5 inch rectangular port design optimized for smooth air transition and minimal turbulence at the manifold interface. The absence of an upper bolt hole simplifies installation on certain BBC configurations while reducing potential stress concentration points. Composite construction provides superior temperature resistance compared to traditional cork or rubber alternatives, enabling consistent sealing across repeated heat cycles without degradation or creep.

This gasket is essential for big block Chevy engine rebuilds, performance intake manifold upgrades, and restoration projects where factory gasket specifications no longer meet modern reliability standards. Proper installation requires careful manifold surface preparation and correct torque sequencing to ensure optimal sealing. The BBC Rect Port Int Gasket W/O Upper Bolt Hole .125 is available for immediate purchase and carries the precision tolerances and material integrity expected in professional automotive and performance engine applications.
