4.00 standard bore competition gasket for cast iron or aluminum cylinder heads on 302 and 351W production blocks. Features solid metallic core with wire encased combustion chamber seal for applications. Surfaces are Teflon coated.
Several different water hole patterns have been used on 302 and 351W Ford Racing cylinder blocks and heads since their introduction. Enine assemblers should lay the head gasket on the block and the cylinder head (with front of 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 inthe block or head or punched in the gasket.
