just having a thought about copper gaskets again,
i was sure copper reacts with aluminum so i had a quick search on the net.
"Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.) Almost any text or handbook on corrosion will have galvanic series table. The farther two metals or alloys are separated on the table, faster the corrosion of the less noble of the two will be when they are in contact."

so surely copper head gaskets are a bad thing, also copper doesn't and wont compress like the OEM gaskets do so there cant be any imperfections on ether surface,
but then i think copper washers are used for air and water tight fittings as a "gasket" as such so copper does have its sealing quilatys
so my question is the pros and cons of copper good or bad ?? what would be the advantages over the OEM gaskets.
maybe is should start a new thread ??
