Head Gasket situation

If your set on wanting a set of MLS gaskets that will work with the early notched cylinder heads, Victor Reinz makes a set. (I don't blame you)
MAHLE Clevite offers technical information regarding gasket replacement for GM LS series engines.
The Issue: When the OE composite designed cylinder head gasket changed to an improved Multi-Layered Steel (MLS) design for the 4.8L & 5.3L in 2001 and 6.0L in 2002, the cylinder head gaskets were no longer interchangeable. This prevents engine builders and technicians from installing the best MLS designs in older engines of the GM LS series due to resulting coolant leaks.
The Resolution: Through vigorous testing and analysis, Victor Reinz has engineered a replacement MLS gasket design that fits GM Gen III 4.8L, 5.3L (1999-2000) and 6.0L (1999-2001) series engines. These gaskets accommodate both the early and late style head design. Additionally, the MLS design features an embossed stainless steel stopper layer. Victor Reinz utilizes state-of-the-art Intellicoat™ blue FKM elastomer coating on the “active” layers. This special coating is recognized for the outstanding ability to seal the head and block mating surfaces (up to 60RA) without the need for exotic surfacing equipment and techniques.
The Application: GM LS series Gen III and IV, 4.8L, 5.3L, 5.7L, 6.0L and 7.0L from 1999 thru 2009 are covered with these four new part numbers:
54441 - GM 4.8L VIN V, 5.3L VIN P, T & Z 1999-2007
54442 - GM 4.8L VIN C 2007-2008, 5.3L All VIN except P, T & Z 2005-2009, 5.7L 1997-2005
54445 - GM 6.0L VIN H, N & U 1999-2008
54446 - GM 7.0L 2006-2008
Consult your Victor Reinz Gasket Catalog or your local distributor for exact application/part number detail.
