For my bench grinder I use a piece of so called Quartz to dress the wheels: https://www.mad4tools.com/silverline-sil...el-dresser
A chunk of silicon carbide like this is also really useful for re-shaping mounted grinding points for doing porting where 'off the peg' items are often not the right shape or size for the profile you might want to achieve.
But for precision grinding stones such as those on the Vibro Centric tool or the valve grinder, it really needs to be a jig mounted single point diamond run across the surface. In the OP's photo, the jig for the seat grinder stones appears to be the angled spring loaded plunger; the single point diamond would be fitted at 90 degrees to that plunger.
