Best Rubber Valve COver Gasket?

[PHOENIX]

I plan to change the valve cover gaskets soon.

I currently have a set of the orange Fel-pro gaskets on there ($20-30).
They have the black plastic insert in the center.
They also have the little ridges along the gasket.
My current covers are most likely bent and causing the leak.
I have an extra set of these gaskets, but was thinking of trying something else. I do not like the ridges in the gasket. I would prefer a consistant solid shape, like stock cork gaskets. Does anyone make a rubber valve cover gasket like that?

Price is not an issue. I am tired of the leaks. Plus I have some nice cast covers that should distort less and give a better seal.
