I found a kit with the gasket you are talking about...the one i found doesn't even include the round gasket. I know my gasket kit, which was from Moose, only had the round gasket. I think the eye shaped you are talking about is in cheaper kits or something, the one I found looks to be cheaply made.
I know you definately need the round gasket, because it fits into a groove on the exhaust port. I don't see how the other gasket would seal the exhaust to the motor.
Hope this helps.
