I would not use Scotchbrite discs on any flat machined surfaces. Scotchbrite has an abrasive component and you will no longer have flat surfaces. This is especially important on the head gasket surfaces which must be flat to seal properly.
Also Scotchbrite is introducing an abrasive in the engine components and you have to be sure everything is absolutely clean and every bit of the abrasive is removed or you can wind up with abrasive inside the engine.
My opinion,
