    When a compression ring pushes out on a head gasket continued use will mar the head. It looks simalar to a blow torch on steel. If the block surface is torched it will be difficult to seal a head gasket. from mobile

    It depends on what turbine size a/r housing, wastegating etc. We really need to start posting cw and tw size plus a/r. such as a t6 s475 would be 75/96/1.32 cw-inducer/tw-inducer/ turbine housing a/r. THE FORD AND DODGE GUYS DO IT AND IT MAKES LIFE A WHOLE LOT EASIER!
