For copper o-ring as a head gasket, the machine shop will cut the block to allow for the copper o-ring to be insterded but when it's cold out copper will leak. Also it can work great or give you issues.
The head gasket that I'm using is a mls cometic head gasket.
As of right now the CP pistons and head gasket will take about a month to make. This is the busy time for both company's.
