question about cleaning carbon out of ring grooves , I have been reading a lot about using fine walnut shells to clean some parts including ring grooves

what is very one thought on this , it seems like it would make life easier ?

I use a broken ring from the engine I'm disassembling.  When available, I use the dip type carburetor cleaner to soak the pistons that are really carboned up.  It will soften and remove most any carbon to varnish with a scrub brush and soapy water as a final cleanup.

BE SURE TO USE EYE PROTECTION, GOOD GLOVES AND EXTREME CARE  when using dip type caustic carb cleaner.  It's great on aluminum and ferrous metals, but it will remove many layers of skin, (down to the bone) if it makes contact and it'll do it really fast.

I made tools that fit in a drill motor to drive the oil pump after the engine is assembled.  I run the oil pump to prime the entire oil system and that usually pumps up the lifters too. Run the pump 'til you see the rocker arms move slightly. Then turn the engine just a full turn and run the pump again.  When you're through, you can set the engine on TDC and install the distributor.
