6.0L Power Stroke Head Gasket Set, 20mm dowel

20mm cylinder-head dowels: engines built 2006-01-16 and newer (Ford catalog: 'From 01/16/2006', '20mm Dowel Holes') - late-build MY2006, all MY2007 pickups, and E-Series from late-MY2006 builds through 2010 ('E350 vans' is in the catalog application). Verify by build date, measurement, or head casting number (1870389C1). Ford PNs: bare gasket 6C3Z-6051-AA (Intl 1858190C92); Ford KIT (2 gaskets + standpipes + dowel pins + head bolts) 6C3Z-6051-BA. A step dowel (Ford 6C3Z-6B041-B) lets 20mm heads seat on an 18mm block. ORDER-TIME NUANCE 2026-09-08: the catalog description for -AA also says 'Incl. Head Bolts' while community lists treat -AA as the bare gasket and -BA as the kit - confirm bare-vs-kit at order time. Break date refined from the vendor-cited 2006-01-11/12 to the catalog's 2006-01-16.
