Hey, if you want i can check out your tune that is in your truck to see exactly what your running and how it is set up... I am no expert but i can tell you if your tune is good or bad...

 

Hey bigboy don't forget to save a little cash for some new rear tires bro. If i remember right, they were pretty spent...

 

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.

 

ya corey that would be cool especially if we can get together and do it before i get retuned to see what changes need to be made or if anything even needs done..... Yea my tires are shot the polyester is showin that could cause some damage! Hopefully i wil have everything up and going before feb 20. so i can make it down to the SAR Meet

1Bear Do you have a website that i can look those gaskets up i googled them and didnt find nothing..

 

I've used factory MLS gaskets with nitrous, and never had a problem.

 

Thanks Chase i figured as cheap as they are more people would have commented on them..

 

I'm sorry, but I sure don't. I have never used them either, I just knew they existed and had that little bit of info on them and wanted you to know that you possibly had an option.

 

ebay, has a few stores that sell them.

 

Sure thing just let me know next time your up and running and we will figure something out

 

Don't get me wrong, I think the cometics are better. But they are pricey. I used LS3 gaskets on my car, and I think they were $23 a piece.
