Dremel on the block head?

In the middle of cleaning the block for a new gasket with a very light application of a dremel and 240 grit sanding pads which is making slow progress.
Does anyone have tips for this?

I’m also concerned about the ‘burr’ from the piston edges. Is this original? Is this removed if you have the head milled? And if so should I be leaving the crusty piston edges or continue to try to get them clean and smooth?

Okay awesome, I didn’t think a nylon one would do the job but I thought a steel one might scratch the head. Thank you for the link!
