Copper head gaskets are only good if you don't feel like spending money on standard head gaskets during an overhaul.
One of the most important factors in getting a copper head gasket to seal is having the head and cylinder surfaces perfectly flat.
If they're both perfectly flat, you won't have near the difficulty in getting a copper head gasket to seal.
If a copper head gasket is leaking, chances are a regular head gasket will seal up just fine.
Having the head O-ringed is the best solution if you don't feel like buying lots of head gaskets.

Also if you have a cool head, make sure each stud has the copper washer on it.

Throurghly clean it off with acetone. I will need to be re-anneled in an oven, not sure on temp or time. Let cool, put on rubber gloves, completelt clean again with alcohol, keep the gloves on, apply a thin even layer of permatex ultra grey semi-rigid sealer use only ultra grey. put the gasket back on and torque properly in sequence. You use the rubber gloves because the oil from your finger gets on the clean copper and then the sealer won't stick to that spot were your oily finger was. the gasket needs to be completely clean before the ultra grey. I personnally hate cooper gaskets and would just get a cometic with a thin layer of ultra grey on it. The copper gasket offers no benefit over a quality stock style gasket and seem to have a lot more sealing problems than any other head gasket. The best fix is send it out and have it o-ringed.
