Headgasket differences?

[DeNoZZo]

I recently ordered a cometic mls headgasket from a vendor and it doesn't fit. It does not match my previous cometic mls headgasket and some of the coolant/oil passages don't match up. Is there a difference between the 6 and 7 bolt headgaskets?

What is the part number? It sounds like you have an evo headgasket.
