If it's a race engine & gets torn down frequently full copper is OK.

Otherwise, conventional graphite and steel laminate I would think work just fine. JMO.

Yes. I have heard of others having coolant seepage when using using solid copper - especially if the surfaces aren't perfectly smooth and square. The Best gasket is constructed from two .010 sheets of copper laminated onto graphite core:

But since this is a street build I guess I will just go with the conventional gasket.
