FAQ
Is this the .020″ over-thickness set?
Yes. HS4068B is MAHLE’s .50 mm (.020″) thicker head set for the 5.9L 12V Cummins.
When would I use the .020″ over gasket?
When head/block machining or service specs call for additional thickness to maintain proper piston-to-head clearance and compression.
Does it include head bolts or studs?
No. Reuse only if within spec or upgrade to new bolts/studs.
Do I also need the lower set?
Yes, if you want a full engine gasket overhaul. Pair with CS4068 (lower set).
