Cometic Ford 239/255 Flathead V8 3.375in Bore 24 Bolt .027 in MLS Head Gasket - Right

If you're rebuilding the top end of your Ford 239 or 255 Flathead V8, this Cometic MLS head gasket is a solid choice. It's specifically made for the right side of the engine and features a 3.375-inch bore with a 24-bolt pattern, a common setup for these classic V8s. The gasket thickness is .027 inches, which is a standard dimension for many rebuilds, helping to maintain proper compression ratios.

This gasket uses Cometic's HP shim technology, which is designed to increase the clamping force around the combustion chamber. This is particularly helpful on open deck block designs, like those found in many Flathead Fords, to ensure a strong seal. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and oil, helping to create a reliable seal against combustion pressures and engine fluids.

This gasket fits a wide range of Ford and Mercury vehicles from the late 1940s through the early 1950s, including models like the Ford F-1, Ford Customline, and Mercury Monterey. Make sure you order the correct gasket for the left or right side of your engine, as they are sold individually.
