I have finally started to tune my car and as I started tuning everything was fine. About an hour into tuning I noticed my head was puking oil... I'm positive it's coming from the headgasket. the head has been decked and the block was just cleaned and checked that it was flat. I have ARP head studs, metal headgasket from a 20vt, and copper spray on the gasket so I am pretty sure all I have to do is retorque the head studs and I should be fine? Anybody have any tips or ideas? I have never had a metal headgasket not seal so I am kind of frreaking out...
