Product Details
If you're working on a Ford 302 head on a 351C block, this Cometic Multi-Layer Steel (MLS) head gasket is built to seal that combination. It's designed with a 4.150-inch bore and a .051-inch thickness, specifically for that unique engine build. This gasket fits a wide range of Ford vehicles, including classic Broncos, Panteras, and Econoline vans from various years.
The key here is the HP shim technology integrated into the gasket. This feature increases the clamping force around the combustion chamber, which is especially important for open deck blocks. It helps ensure a solid seal, preventing leaks and maintaining compression. The outer layers are also coated with Viton, a material known for its resistance to heat and oil, further enhancing the gasket's ability to hold up under demanding conditions.
