copper head gaskets
I was on honda-tech reading about this but I'm still not fully understanding what needs to be done. My buddy blew his head gasket and we now have a copper one that we want to replace it with. What exactly do we need to do, mill the head? Get new head studs? O-ring the head? Any help would be great.

Re:copper head gaskets
Yup need to get the head o-ringed.
But a friend of mine has come up with an idea that needs to be tested on his car first....no o-ring!??
And use the copper spray it is worth it.
Here they use copper spray only and no head gasket on motorcycle heads for race only to up the copression.

Re:copper head gaskets
Correct, you cannot just slap a copper gasket on a stock head/block. It needs to be stepped, or O-ringed, otherwise it will NOT Seal. You can have the oring placed on the head, or around the sleeve itself, but its a bit tricky to cut a groove on the sleeve. The o-rings will have to be hand made, and filed perfectly.
For best sealing, you can make 2 grooves one head and once block, one will be a reciever grove.
I also recommend using copper Spray on the headgasket itself when doing this.

Re:copper head gaskets
Resurfacing the head only really needs to be done when the engine gets overheated, (basically it warps) Its up to you if you want it to get resurfaced (milled)
Advantage for a stock gasket?.. Well they do work pretty good, especially the tripple layer metal ones. Some people like cometic gaskets, but I have never tried them.
