copper is great. Except you have to be more meticulous, particuilarly making the the surfaces contacting the gasket(block and head) are very flat. Copper is a softer metal, so it can do a good job sealing, but is not nearly as soft as a felt gesket. Felt gaskets can deal with a lot more imperfections. But copper will be much more resistant to blowing out. But it is overkill unless you expect to run into some moderate to heavy detonation on a regular basis.
