Several different water hole patterns have been used on 302 and 351W Ford Racing cylinder blocks and heads since their introduction. Engine 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 in the block or head or punched in the gasket.
Water holes in the gasket match blocks produced after May, 1994. Earlier blocks require 8 lower and 6 upper holes to be drilled and 4 holes plugged. Use gaset for template.
