If so, do you have problems with sealing?
i.e. oil leaks? I have been told this is common and exceptable. Combustion chamber sealing? leakdown to an adjacent cylinder? Did you have to re-torque the head many times?

 

I was considering doing that, but i remember someone saying that they had problems, so now i don't know if i want to do it. I want to know too, so bump for you.

 

Copper head gaskets are amazing, they seal compression like no other. This is why most (all) race motors run them. the downfall? they won't seal water for ****. Leave full copper gaskets to drag race cars that just fill the block with water, then drain it after the run. There are some gasket kits out there (like fel pro) that will have copper rings around the cylinders, though, not sure about for hondas...

 

it would depend too on what kind of coolant your using...some coolants will attack copper and begin to corrode it.
