55-86 SBC V/C Gasket (pr)

The 55-86 SBC V/C Gasket from Specialty Products Company is a matched pair of valve cover gaskets engineered for Small Block Chevrolet engines. Anyone maintaining a classic or contemporary SBC-powered boat, truck, or street machine knows that a reliable valve cover gasket is essential to prevent oil seepage and maintain engine integrity. These gaskets seal the critical interface between the cylinder head and valve cover, protecting internal engine components from contamination and oil loss during thousands of operating hours.

Constructed with a steel core silicone rubber compound and precision-machined to 0.188 inches thick, the 55-86 SBC V/C Gasket delivers superior durability and thermal resistance compared to standard cork alternatives. The steel reinforcement prevents gasket material deformation under engine vibration and thermal cycling, while the silicone rubber formulation maintains flexibility and seal integrity across a wide temperature range—critical for marine environments where engine bay conditions fluctuate rapidly. The gasket pair ensures both sides of the valve cover assembly are properly sealed, eliminating sources of oil weeping that can compromise engine appearance and performance.

This gasket pair is ideal for boaters and engine enthusiasts restoring or rebuilding SBC powerplants from 1955 through 1986, though compatibility extends to any Small Block Chevy configuration using original-style valve cover geometry. Installation is straightforward: remove the old gasket material, clean the mating surfaces thoroughly, and seat the new gasket before torquing the cover in a cross pattern. Proper installation ensures a watertight seal that will outlast the engine's service life in saltwater, freshwater, or terrestrial applications.
