Removing header gaskets

[jamie]

Hey guys, I'm replacing my header gaskets after recently fitting a wideband to my exhaust. After looking at the exhaust port, for me its hard to tell what the gasket looks like. I dont wanna start sticking a flathead screwdriver in there if i don't know where to start prying. Any ideas how to get them out? Shouldn't be hard, the bikes' only 4 months old.

Many thanks
