What's most efficiant way to remove the gunk and grime from the block area where the heads mouth up? Also need to clean the top of the pistons. Any suggestions?

Engine degreaser or brake cleaner for the external of the block and use water to wash it off - i always follow suite with a rag to remove any moisture around gasket areas that can be reached. If the block has been enamel coated/painted you cannot use brake cleaner as it will take the engine enamel coating right off.
Carbon buildup i normally use carb cleaner, gasoline, or seafoam on a rag. Wipe down with oil - turn the motor over a few times, and do the next. Change the oil after you're done.

Why would you need an air grinder and abrasive pads? Brake cleaner and a stiff tooth brush, a bag of rags on sale at the local hardware store, insert your favorite whistle wetting beverage, and alot of elbow grease is all you need. You may need to clean/rinse/wipe/repeat as necessary as well. Let it soak a bit if it is that hard to get off. If you still want to use a tool do not use air grinders as they are too fast of an RPM - use one of those battery powered electric drills for more control. plastic or brass is good but not steel brushes - you cant control where the bristles go when they break.

Do you know what the grit counts are? I did a bit of looking and found nothing. I would think any heavy grit followed by polishing would cause un-even finish on the piston which could effect squish. Depending on the grit counts though it would not cause a problem.

The discs are plastic so you can grind all day and they won't mess up aluminum...green discs are for steel only, but yellow and white are good, I usually use white just to be cautious...they aren't like the Brillo material they are plastic disc with fingers I believe they are called rolox discs. I got mine at paint and body store
