In non turbo form it is common to skim 2mm off. With turbo I would not want to take more than 0.5mm combined off

Unless you are building something special use the normal head gasket. If you are building something special then your engine builder will work it out for you

It is turbo 0 .5 won't be enough to clear the pitting

Best bet is to weld up the pitted areas before machining
