Rolo disc scotch bright
Do not use rolo disc on matting surfaces every time I bring something in with disc marks on it the Machinist cusses me out, it removes lots of metal. Now if you have had the heads surfaced then they have migrated down. The engine shop I use always checks the surface and mills the manifold if it does not sit flat or not down on the valley. Yes I know the boys at the dealership use the rolos to clean, but I don't like them all that much.
