Customer q:

I have a pre- 2004 6.0L LS motor that I had bored .030 over and it is now a 370 cubic inch. My question is what is the part number for the GM MLS head gaskets that will work for my application?


ac = Yes

drivewheel = 2WD

engine = 6.0 Litre Ls

fuel = fuel injected

make = chevy

model = camaro

pwrbrk = Yes

pwrstr = Yes

trans = automatic

year = 1998


Thank you for giving JEGS the opportunity to assist you. 

The GM MLS head gaskets would be part number - 809-19170418. If you are concerned with losing compression due to the large 4.100" bore size on the GM gaskets I would recommend using Cometic LS1/LS6/LS2 gaskets they are available in 4.060" bore, which is still bigger than what you really need, but they also have a wife range of compressed thickness options .030" - .120" - Cometic-LS-Series-Cylinder-Head-Gaskets (the part numbers for your engine will start with 245-C5751-)You can place your order online at www.jegs.com, speak with Customer Service or request Technical Assistance via telephone at 1-800-345-4545 . 

We look forward to assisting you with your project in the future and if you have any additional questions please feel free to contact us.
