Cometic Ford 239/255 Flathead V8 3.375in Bore 24 Bolt .060 in MLS Head Gasket - Right

If you're rebuilding the top end of a Ford Flathead V8 from the late 40s or early 50s, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made for the 239 and 255 cubic inch engines with a 3.375-inch bore, and this is the right-side gasket, designed to seal the cylinder head to the block effectively. These gaskets are built to handle the demands of engines that might be running a bit hotter or under more stress than stock.

What makes these MLS gaskets stand out is their construction. They use multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating, along with the embossed layers, helps create a strong seal without needing any extra sealants, making installation a bit more straightforward. The center layer can be varied in thickness, and in this case, it's set at 0.060 inches to achieve a compressed operating thickness of 0.098 inches, which is important for maintaining proper compression ratios.

This gasket is designed to work well with both aluminum heads on cast iron blocks and aluminum heads on aluminum blocks, as it can handle the shearing forces that can occur between different metals. It's a well-built component that offers improved sealing performance for your classic Ford V8 project.
