Assembeling a 99' yz400f. The cometic gasket set that came looks as if it was not stamped for the water jackets.:doh: I tossed the used gasket long ago so i can not compare the two. I think there suposed to have water jacket holes, Any one have yz400f head gasket pics?.... What do you think?

That gasket HAS holes for each of the water jackets. The variation in the size of the holes is common, and is done to control the flow rate and direction through the head. I don't see a problem.
