| Grade c will be fine regardless of what came off originally. Like said above, the torque sequence should be in the box on a piece of paper

| These heads do not have combustion chambers. So why does milling the head effect the required gasket thickness? Is it because of the valve seat depth from the cylinder head face?

| Head gasket thickness is based off of piston protrusion. If the heads are done properly and the valves set within the factory service limit there is no change in piston to valve clearance.
