Product Description
MAHLE HS54579 cylinder head gasket set delivers OE-level sealing for late-build 2006.5–2007 Ford 6.0L Power Stroke engines with 20 mm dowel pins. This complete top-end set includes Black Diamond™ MLS head gaskets plus the intake/exhaust and upper-engine seals needed to finish the job with confidence—ideal for towing, work-truck reliability, and long-term durability.
Fitment

FAQ
How do I know if my 6.0L uses 20 mm dowels?
Late-2006 to 2007 builds typically use 20 mm. Measure the head-locating dowels or check the engine tag. If it’s 18 mm, use HS54450.
Does HS54579 include head bolts or dowel pins?
No. Add MAHLE GS33494 (two kits for both heads). Dowel pins are not included in HS54579; an individual gasket like 54579A may include pins.
