Copper head gaskets are typically less forgiving. They're commonly used in high-performance applications. They are re-usable, although they have to be re-annealed. They seal combustion well, but they are prone to leak coolant. They're less forgiving to imperfections in the head and deck surfaces. | Copper head gaskets are typically less forgiving.

You'll also need a good sealer around the water passages. | + | To take full advantage of copper head gaskets, you have wire o-rings machined into the block or the head ''(confirm and expand)''.
