I have 1 Standard thickness MLS headgasket and 2 oversize that I don't need. The best I can tell the oversize gaskets are .005-.008 thicker than the standard gaskets. With a set of calipers it reads different depending on where you take the measurement. I'm not sure what Cummins official size is but can check if I need to. The standard size gasket is a 3958644 and the oversize is a 3958645. 60.00 each plus shipping.
