Is this engine specific or general for any engine? I've never heard the term either.
Deutz air cooled diesels required a piece of solid core lead solder to be crushed between the head and piston after the head is bolted on, then it's removed and miked to see the clearance since it doesn't use a head gasket. The cylinder to head seat carbon seals itself like an old VW engine. (A few others also use that method)
Pencil type injectors (cat/perkins etc.) also have a crush washer on the face seat to seal them and it could refer to that.
