FAQ

Does this include head gaskets?

No. This is the complete engine gasket set without head gaskets and without head bolts.

Will it fit my 2004 LLY?

It fits late 2004.5 LLY (mid-year changeover). Verify VIN “2” and production date.

Are the exhaust manifold gaskets MLS?

Yes—multi-layer steel is used where required for durability (e.g., exhaust manifold locations).
