Ford Performance Boss Block Head Gaskets - 4.00" Bore - 5.0/5.8
Whether you need to replace the head gaskets due to cracks or blown-out seals, this Boss Block head gasket kit from Ford Performance will seal your 1979-1995 Mustang cylinder heads properly. Ford Performance designed this head gasket kit specifically for the Windsor-based 5.0/5.8 Boss Blocks, featuring a solid metallic core design with a wire-encased combustion chamber seal for a superior primary combustion seal. The head gaskets are constructed to maintain their shape under thermal expansion as well, and the PTFE coating helps ensure a tight seal. Install these Ford Performance competition head gaskets on your Mustang with confidence, knowing they are made of high-quality materials!

Head Gaskets Specs:
  • Bore Diameter 4.00"
  • Gasket Diameter 4.100"
  • Compressed Thickness 0.040"
  • Compressed Volume 8.8cc

Boss Block Note
  • Several different water hole patterns have been used on 302 and 351W Ford Performance cylinder blocks and heads since their introduction. Engine assemblers should lay the head gasket on the block and the cylinder head (with the front of the gasket toward the front of the engine) to make sure there is a path for coolant flow from the block into the head. In some cases, holes may have to be drilled in the block or head, or punched in the gasket.
