Oil & Steam Passages
This shot shows the block with the gasket sitting on it. You can see the oil passage offset for the head as well as added holes in the NAPZ24 head gasket for steam holes added to the block and gasket for the L head. Using the NISMO gasket eliminates the need to add holes to the gasket. The oil feed hole in the head is located at the other side of the slot in the gasket. You can use a die grinder to elongate the oil feed hole in the head to match the slot on the gasket.
