330-455 Olds Exhaust Gsk 1964-1979 ENGINES

The FEL-PRO 330-455 Olds Exhaust Gasket Set is a pair of precision-engineered manifold gaskets engineered for Oldsmobile V8 engines from 1964 through 1979. These gaskets seal the critical joint between the cylinder head and exhaust manifold, where combustion gases reach temperatures exceeding 1,200°F. A failed or degraded exhaust manifold gasket allows unburned exhaust gases to escape, reducing engine efficiency, increasing fuel consumption, and creating diagnostic headaches during emissions testing or performance diagnostics.

Each gasket features a 1.560 x 1.950 inch rectangular port design with a steel core laminate construction—a multi-layer design that resists blowout under sustained high temperatures and thermal cycling. The laminated steel core prevents deformation better than pure asbestos alternatives, particularly during aggressive driving or after engine modifications that increase combustion pressure. FEL-PRO's manufacturing tolerance ensures precise port alignment with OEM manifold specifications, eliminating leaks that would otherwise require re-torquing bolts or complete manifold removal.

This gasket set is purpose-built for 330-455 cubic inch displacement Oldsmobile engines—the workhorse V8 platform used in full-size vehicles, muscle cars, and towing applications throughout the 1960s and 1970s. Technicians restoring original equipment, replacing worn factory gaskets, or rebuilding older Olds powerplants depend on FEL-PRO's OEM-level engineering for reliability. Installation requires removing both manifolds, cleaning the sealing surfaces, and torquing bolts to specification—a straightforward job for anyone with basic mechanical skills and the right tools.

For vintage Oldsmobile owners and engine builders, original-specification gasket sets are essential. FEL-PRO's heritage as an OEM supplier means these gaskets meet the original equipment standards that kept 330-455 engines sealed for decades. Stocking the correct gasket set eliminates multiple trips to the parts store and ensures the exhaust system seals properly the first time.
